All the best in 2018!

  Hope you all had a great holiday season to round up 2017 with great family time. During the holidays I was able to meet all of my living ancestors, as well as all of my siblings and their kids, so I am definitely satisfied.

What I want to achieve in this blog post is wrapping up last year with the evaluation of my 2017 goal set, so I can improve setting up a more realistic 2018 list.

Let's shortly revise what I set up to:

1. Have a healthy son introduced into the world. 
2. Improve the family tree. This has subgoals as per the latest 2016 balancing blog.
   2.1. Identify 40% of ancestors up to 10th gen - identify 818 ancestors (out of 2046).
   I currently [think I] know 512 of them. This means 306 new ancestors in 2017.
   2.2. Identify half of my paternal grandfather's 7th generation. I.e. 64 ancestors. 
3. Run a Czech series for newbies in genetic genealogy. 
4. Break one or both of my closest brick walls.
   4.1. This includes a sub-goal of gathering as much relevant samples as possible.
   4.2. Work on recombination map and chromosome coverage on paternal side.
5. Test my own children.
6. Start an "Ancestor of the week" feature - were I blog about one of my ancestors.
7. Keep working with my genetic genealogy matches (this includes 23andMe matches and the relevant goal mentioned in the recent 2016 balancing blog).

Let's start with the resounding successes:

1. Have a healthy son introduced into the world. 

Yes! Vitus is not only a great boy (he can already say "daddy"), I was able to deepen the knowledge of my paternal ancestry driven by my first born son - here. 100% complete

2.2. Identify half of my paternal grandfather's 7th generation. I.e. 64 ancestors. 

By very focused work, I was able to just achieve this goal! Yay!

7. Working with genetic matches.

I was definitely active in this direction and was able to map several US cousins to my tree (usually by building their own tree in the process).

On to the partial successes:

2.1. Identify 40% of ancestors up to 10th gen - identify 818 ancestors (out of 2046).

Well, today finds me at 635 ancestors. Some somewhat hypothetical. That is not too bad of a growth from the 512 I had last year (24%). I guess my goal was just too aggressive.

If I want to aim at another 24%, my goal for 2018 would be 788 ancestors.

3. Run a Czech series for newbies in genetic genealogy. 

This was a very small success at the last minute. I ran a blog about the most common Czech DNA test - Genetics and Surnames project.

4. Break one or both of my closest brick walls. 

Based on DNA testing, I now have a candidate father for my great-great-grandfather, Antonin Sula, 1871. The new supposed ancestor is Frantisek Skrejsovsky, 1837.

Further testing will be needed to verify this hypothesis.

The other MPE will be harder to identify, as there is quite heavy endogamy in the Hornacko region, and lack of Czech testers.

5. Test my own children.

This was another last minute save. We sent out my daughters tests to 23andMe on Dec 23rd. It was a pleasant surprise that my 3 year old was able to spit enough (not verified by the lab).

My youngest remains untested. I am kinda on a lookout for FTDNA move to GSA chip...

Total failure:

6. Start an "Ancestor of the week" feature - were I blog about one of my ancestors.

Well the Ancestor of the week is the only thing I have not managed to start in 2017. Hopefully, I can do better in 2018!

With that I am looking forward to the 2018 plan post and hope you all had better success planning your goals than I did.

23andMe move to the New Experience coming!

So 23andMe has finally gotten to transitioning foreign accounts WITHOUT health information - sorry UK, Canada or Denmark.

What will it bring? Worse ability to work with DNA relatives :( That's the biggest bummer, the new interface is more newbie oriented and does not offer as quick and outcome oriented  capabilities as the old one. Also, the 529andYou chrome plugin does not work perfectly (at least yet), that is going to be a big downside. I only like 23andMe most to work with, because of the powerful plugin 529andYou made work with triangulations so effortless.

On the other hand, we have a lot to look for.

1. Accepting invitations, yay! Yes I had my account bugged for maybe 4 months now, unable to accept any invitations from others.
2. Reading and writing messages! Yipeee!! Again, my account, due to it's size, probably, was no longer able to read new messages from people. Sorry everyone! 
3. Contacting Anonymous matches! Finally, we will be able to contact anonymous people again. They often do not know they are anonymous and are perfectly fine with sharing.
4. New In-Common-With functionality. Huge! I am so looking forward to learning where do my anonymous matches fit. And others as well.
5. All other little nice things like updated male haplogroups.

I want to take this opportunity to run one last invitation wave on the old site. Who knows how things will be, and one thing is clear. Any matches you have persist through the transition.
So clearly matches = good :)

If you are my match checking up here, I would love to help you understand genetic genealogy or be able to understand your Central European, or even Czech ancestry better.
Still, if you are not interested in any of that, and can just approve my sharing request, that will help me a bunch in my family research. It will enable me to better define triangulations, portions of my and my matches' DNA coming from a specific ancestor. This will only show me a very small portion of the DNA we share and poses no security risk.

I would also like to do an update to my matches series. Where did we get since January first?

Let me compare against the last blog series from December 28th:

	DNA matches	Anonymous	Accepted	% accepted
me (Kuba)	952 (+6)	214 (-25)	381 (+21)	40.02%
mother	854 (+9)	239 (-32)	311 (+25)	36.42%
father	918 (+2)	196 (-33)	391 (+30)	42.59%
m. grandma	1122 (+19)	293 (-9)	516 (+21)	45.99%
p. grandma	925 (+5)	241 (-34)	337 (+11)	36.43%
m. grandpa	957 (+14)	229 (-28)	357 (+23)	37.30%
wife	898 (+8)	224 (-50)	304 (+29)	33.85%

What is important to say, is that this was without any invitation messages being written. Nada.

And we're still breaking the magical 40% accepted on some kits already! Sweet.
Despite the negative sentiment everywhere (facebook, forums), I can still report number of matches growing on ALL of my kits.
WHILE, number of anonymous matches dropping, sometimes at a speed of light - 50 anonymous matches disappearing from my wife's list. WOW.

Simple observation. As long as you keep inviting your relatives to share, you should be good. See more and more cousins to research.

So where are we with unaccepted matches? Let's see:

Hm, 6 bugged invitations. Hope they stay for the TNE.

And over three and half thousands of unaccepted invitations. Including some of the closest ones. I sure hope this invitation round will reach to some of these cousins. Getting down to 3000 would be awesome ;)

So let's look forward to the New Experience with positive attitude. There are some great new features in there. As well as a renewed possibility to connect with anonymous matches.

And last but not least, I am working on my tree hard (as time permits) so I can find a connection for all of these new matches :)

Goals for 2017

First and foremost: Happy New Year! 🎉🎉🎉 May you all have a very successful 2017 with lot of genealogical successes, uncovered DNA cousins and healthy family members.

A new year is a great time for tidying up and starting afresh with new vigor.

So what are the goals I want to achieve? I have already mentioned some of them in my last two blogs, but I will incorporate those into the overall list with order by importance.

1. Have a healthy son introduced into the world. Yay! This is not strictly genealogical, nor strictly genetical, but taking care of my newborn son will be a great experience in 2017. It will take away some of my free time - so excuse in me in times of silence. Importantly, here comes a huge thank you to my wife, for being such an excellent person and mother. Love you, honey 💖
   
2. Improve the family tree. This has subgoals as per the latest 2016 balancing blog.
   
   2.1. Identify 40% of my own overall ancestors up to the 10th generation. This means identifying 818 ancestors of mine (out of 2046). I currently [think I] know 512 of them. This means identifying 306 new ancestors of mine in the new year 2017.
   
   2.2. Identify half of my paternal grandfather's 7th generation. I.e. 64 ancestors. This is an ambitious plan, as I have not reached 64 ancestors on this level for none of my other grandparents. But it is important to aim high.
   
3. Run a Czech series for newbies in genetic genealogy. (This will probably be Czech only - there is a lot of existing English material and maintaining bilinguality costs a lot of time and energy).
   
4. Break one or both of my closest brick walls. One of my paternal grandmother's great-grandfathers is unknown, as well as one of my paternal grandfather's great-grandfathers. Attacking them with autosomal DNA was the goal from the beginning, so identifying one or both of them would be a tremendous achievement.
   
   4.1. This includes a sub-goal of gathering as much relevant samples from those sides of the family as possible.
   
   4.2. Work on recombination map and chromosome ancestral coverage on my paternal side.
   
5. Test my own children. We have agreed with my wife to test the children, so looking into what's the best option and going through with it is one of the topics of 2017.
   
6. Start an "Ancestor of the week" feature - were I blog about one of my ancestors. I expect only a few of these throughout the year
   
7. Keep working with my genetic genealogy matches (this includes 23andMe matches and the relevant goal mentioned in the recent 2016 balancing blog).

I have more on my mind, but let's keep it at 7. I will try to address each and every one of these goals, with the priority going top to bottom.

How did I fare with my family tree research since starting the blog?

So the very first post on this blog wisely talked about family tree being the number one resource and prerequisite for a genetic genealogists work. We have stressed out how most of our DNA matches are probably 8th followed by 7th cousins. And we need a deep tree for that.

Well, the sad truth is I was more distracted elsewhere (e.g. 23andMe sharing series) and haven't done the progress I hoped for, when writing the initial blog post.

Here comes the comparison table:

gen#	rel	match	#anc/gen	#idd me	#idd mgm	#idd mgf	#idd pgm	#idd pgf
2	gp	1C	4	4	4	4	4	4
3	Ggp	2C	8	8	8	8	7	7
4	GGgp	3C	16	16	15	16	14 (+3)	14
5	3Ggp	4C	32	30	30	32 (+1)	22 (+4)	26 (+1)
6	4Ggp	5C	64	59 (+3)	49 (+1)	38 (+4)	27	32 (+7)
7	5Ggp	6C	128	110 (+6)	21 (+5)	31 (+6)	18 (+3)	4 (+1)
8	6Ggp	7C	256	146 (+11)	6 (+2)	46 (+19)	11 (+4)	0
9	7Ggp	8C	512	74 (+15)	4 (+3)	43 (+15)	10 (+4)	0
10	8Ggp	9C	1024	63 (+25)	1 (+1)	8 (+2)	6 (+4)	0

Thankfully, we have made some progress since the first post, signified by the little + numbers in brackets.

Let's first look at the number of my identified ancestors in the light purple (#idd me) column. Our final goal is to have all of the ancestors identified - for this light purple number to be equal to the darker purple number. Up till 7th generation, we're faring well, but then, the numbers fall of extremely rapidly.

We said most of our matches are likely 8th cousins (blue column) and we have still only identified 74 out of 512 possible ancestors. This clearly shows working with DNA matches is going to be frustrating! We need to improve our tree tree further!

Also, I was only talking about my own numbers, but in the 4 white columns, I have included my grandparent's point of view. This is because I am mostly working with DNA matches from the point of view of my grandparents. Here we can see the 8C level is abysmal. We just can't expect finding any common relatives at all, with the trees being so sparse.

Clearly, while I like the DNA work, it is time to sit by the parish records again, and do some serious heavy lifting. I need to call the target for my paternal grandfather (pgf in the table) again, and focus on it this time.

Let me try to shoot for two goals in 2017:

1. Identify half of my paternal grandfather's 7th generation. I.e. 64 ancestors. This is an ambitious plan, as I have not reached 64 ancestors on this level for none of my other grandparents. But it is important to aim high.
2. Identify 40% of my own overall ancestors up to the 10th generation. This means identifying 818 ancestors of mine (out of 2046). I currently [think I] know 512 of them. This means identifying 306 new ancestors of mine in the new year 2017.

All in all, I will try to keep active with the blog but focus on tree building efforts.

State of the year - 23andMe matches

So here it is, yet another calendar year ending. A great time for balancing!
Let's continue with our 23andMe matches series. Please, allow me to present the end of year numbers.

Let me also mention one great tip I got as a reaction to my blog(s).
Do not forget to explain / stress out how sharing with you can be beneficial to the other party! We are not a world of altruistic beings after all, but everyone has their own agenda and goals.

So where do we stand with our 23andMe matches?
One big change happened on my account since November. Now I have both of my parents as part of this same account. This definitely helps in many aspects of genetic genealogy. To remind you, I already had 3 of my grandparents on the account. One might think that the grandparents supersede parents, but the truth is simply the more the merrier - more matches, more IBS uncovered, ...
From now on, we will start including my parents numbers to the table.

Let me compare against the last blog series from November 18th:

	DNA matches	Anonymous	Accepted	% accepted
me (Kuba)	946 (+20)	239 (-20)	360 (+30)	38.05%
mother	845 (+1)*	271 (-16)*	286 (+38)*	33.85%
father	916 (+7)*	229 (-13)*	361 (+18)*	39.41%
m. grandma	1103 (+26)	302 (-21)	495 (+21)	44.88%
p. grandma	920 (+18)	275 (-11)	326 (+21)	35.44%
m. grandpa	943 (+32)	257 (-22)	334 (+38)	35.41%
wife	890 (+8)	274 (-21)	275 (+16)	30.90%

*mother and father differences are since Dec 10, few days after I merged them into a single account.

So what can we see here? Wow, what numbers! The effect of adding father and mother's kit and inviting (no letter apart from generic 23andMe message) everyone is much better than a hand prepared message! Such a positive end to 2016 here.

I newly included anonymous numbers, because many people were commenting on them based on the previous instalments of the series. You can clearly see, anonymous people are disappearing - either making themselves public or disappearing altogether after opting out on TNE ("the new experience" of 23andMe).
I will try to create a short article just covering the anonymous shares in a near future.

The disadvantage of the two additional accounts is more unaccepted outgoing invitations overall:

Will I be ever able to dwindle the number down significantly? Unlikely :( I am still clearly increasing my overall amount of matches, increasing my accepted shares and decreasing the amount of anonymous matches. So that's the most important thing.

Also there is a bug, disabling me from accepting the two pending invitations. Aaaargh. 23andMe know about it, though and are trying to fix it...

I want to create a single 2017 goals article, but let me state some bold goals relevant to 23andMe:

1. Transition to the TNE - this will increase number of matches, introduce open sharing, which should both significantly help with number of known triangulation groups...
2. Move over 40% of accepted shares on all accounts. Ideally breaking 50% on my kit.

Let me wrap it up here, wishing you all a great 2017.

23andMe matches update

  Thank you so much to all my cousins that accepted. It was not a total win, but I think combined with the blog, the campaign was a success. I am sure we will have more accepts in the coming days and weeks.

  So last week, we started at 2793 outstanding invitations, and we were able to bring it down to

2718. Not too bad. But I would prefer 1900 or 900 or 0 :D

Well, it is, what it is. We'll just have to live with this inconvenience of not tapping into the whole 23andMe DB.

So how did we fare on the individual accounts? Let's see.

DNA matches	Accepted	%
926 (+8)	330 (+22)	35.63714903
1077 (+1)	474 (+13)	44.01114206
902 (+4)	305 (+14)	33.81374723
914 (+3)	296 (+17)	32.38512035
886 (+4)	259 (+31)	29.23250564

We did not quite reach the goal of 20/20/20/20/40, but we did not land too far from it. Additional matches over the next week might close the gap for some of the kits.

Again, my kit here is the effect of double dipping - we invite some of these matches twice (my account as well as the grandparent's account) and it can help.

One interesting thing to note for people not aware of this - getting your matches to accept reveals you new matches that are not recent. In the last week, I got between 0 and 2 new recent matches per account, but most of the kits got a few more new matches in their list. Accepting is good for increasing the amount of visible cousins.

It's not only numbers, I got my closest cousin from paternal's grandfather side to accept. Likely a 3C1R of my father. She did not react to follow-up questions and internet searches/ancestry searches ran dry. But I have a nice 5 segment match I can utilize in the future. 

I still have a large backlog of messages to work through, and I am going for that after finishing this blog. That could yield more accepts as well as more identified common ancestors.

The final conclusion is, that even for a European ("Eastern" one at that), you are able to get close to 50% utilization of the 23andMe database, without Open Sharing taking in the account (none available on the old experience). With some basic work, you're able to get around one third of your cousinship to engage (this was only my second invite wave on my wife's account).

FTDNA sales

It's holiday season! Hope you will have a great great time with your family all.

At https://www.familytreedna.com they're giving us some lowest prices in history, to celebrate with some family research.

You can utilize a crowd sourcing document https://docs.google.com/spreadsheets/d/1CgXRKz2TySvRqSInveSIYoslO7yexAc9d-BzpNhaY1c/edit#gid=1338933495 - where everyone is sharing the coupons they do not need.

I can definitely recommend to grab a bunch of those 59$ autosomals, if you're still missing some family members. It will only bring more order in your testing.

If you still miss your mtDNA haplgroup at phylotree.org, I suggest you fix that. An uploaded full mtDNA will guarantee your group being used in any future scientific articles, for great satisfaction and clarity. And if someone with your mtDNA haplogroup is still missing autosomal, go for the combination, easy 10$ :)

And finally BigY. Except of (more expensive) Y Elite at FGC, this is the only possibility to map your paternal line all the way to present. If you have those 400+$ in your genealogy budget, this is one of the most interesting genetic options today. You will create a path for your cousins to follow and your paternal lineage will be researched so much better, than one without NGS testing.

We begin!

  I always thought about maintaining a genealogy or genetic genealogy blog, aimed especially to educate the Czech and Central European genealogist. But also helping everyone fighting with this difficult topic. Additionally, I often find myself wanting to add something to the discussions and idea going around the internet, without a proper channel.

  Today, I want to start with something, every genetic genealogist should put at the front of his efforts. And that is his family tree.

  What we often hear from the testing companies, is 3rd cousin this, 4th cousin that, but the reality of our matches is different. We can visit http://isogg.org/wiki/Cousin_statistics to see, that even with conservative cousin count estimate, we are likely to have more 8th genetic cousins than 7th genetic cousins that 6th genetic cousins and so forth.

What this means for us, genetic genealogists? If we want to find common ancestors with our matches, we need to actually work on our trees! And firmly deep at that. 8th cousins are at the 7 great grandparents level, meaning we have 512 of these ancestors, which amounts to 1022 ancestors including all previous generations from parents up.

For two genetic genealogist, to be able to compare their most likely type of cousin, 8th cousin - they would both need to have 1022 correct ancestors in their trees and compare them.

This goal is probably not feasible in the Czech republic, due to typical time where records fail to be available (end of 17th century). Still I want to be able to track my progress of this goal, and blog seems like a perfect medium.

Let's do this from the perspective of my grandparents first, and then one for me. I wrote a script that pulls this analysis out of GEDCOM, it is not perfect, but being a single ancestor off here and there won't make or break this statistics.

Now it is clear, there is a lot of work to be done, and it is even very visible, where I should start (my paternal grandfather).


Overall, myself, gedmatch ID# M240291 (PM240291M1, PM240291P1)

gen#	rel	~DoB	match	#anc/gen	#idd/gen	%idd/gen	#anc	#idd	%idd

9	7Ggp		8C	512	59	11.52%	1022	416	40.70%

Now having over 50% of 6xgreat grandparents is not terrible, but I am positive much more coverage is achievable.

I will try to publish the progress as it makes sense (few times a year) and we'll see how some improvements of my tree help with the genetic genealogy research :)

Thanks for reading!
