It is always exciting when one of our Y DNA families puts the puzzle pieces together. The De Burghgraeve family has been working on their matches and paper trail and has hit some milestones for triangulating Y DNA ancestors and family lines over hundreds of years.
The image above is from the Family Tree DNA Big Y Block tree. You can see the Burghgraeve matches on the left from Flanders (in Belgium) under R-BY150294. As you pan over to the right, you go farther back in time to meet up with the Winne family (Netherlands) at R-ZP187 and the Stanuszek family (Poland) at R-ZP150 and then farther back to their split from the Wright family (England) in R-ZP125.
Here is what that looks like in the FTDNA time tree:
The FTDNA estimate for R-BY150294 is 1367 CE. That’s the estimate. The family applies that SNP to an ancestor born around 1490 or so. The next SNP down R-BY67888 has been assigned to an ancestor born in 1562. The Big Y estimate is 1511. Not too shabby. The estimate from matching STRs was 1600. Also not too shabby. We would all be lucky to have good paper trails going back this far.
I think it’s best to reference our previous ZP125 conversations after I posted and attempted to correct some faulty age estimates, to get a good picture of the Burghgraeve family and possible connections to the other families under ZP125. https://wanderingtrees.com/2020/02/09/zp125-conversations/
Each of these family connections should make estimates better. As we get more data inside a documented family, it’s easier to assess matches outside the documentation. In that way, Big Y tests for distantly related men help us decipher our connections to other families and the timeline for ancient DNA samples.
When one of us gets a win, we all gain a little more understanding of our shared history.
