Time moves fast in the atDNA world!
No sooner had I prepared an update to the chromsome map showing the atDNA segments identified as being inherited from either Isaac DAWE or Sarah SMITH of Tavistock/Newton Mill/Lumburn, but yet another tested descendant popped up.
Those results haven't been included.
The two updated pages of relevance are:
DNASurnames now has an atDNA section in the DAWE DNA results - which includes a table of relationships as predicted by the shared DNA compared against the known generations to Isaac and Sarah. The table is also interesting in it shows where no detectable match (over 7cMs/700 SNPs) between descendants was found, such is the randomness of atDNA inheritance.
My DAWE family page has the updated Chromosome map included.
The page still includes the 2014 version for comparison -we ARE making progress - wonder how many are the SMITH side?.
Already at least some of the purple segments that were only potentially from the DAWE side of William Rowe/Honor Dawe's ancestry are now identified as DAWE.
The DNASurnames table and segment traceability diagrams can only include those who have uploaded their DNA file to GEDMatch, so neither include the descendant of John DAWE (hatter in Tavistock) and wife Mary FRIEND who popped up on Ancestry as a solid match to myself (Lorna) and also has a smaller match to a descendant of Isaac and Sarah's son Thomas.
Anyone only on ancestry cannot be compared at an appropriate level of detail against the other "cousins" as Ancestry simply does not provide the tools available at either GEDMatch or FamilyTreeDNA.
It would be great to be able to see how likely it is that her John is the John baptized Whitchurch to an Isaac and Sarah.
Working on it, but real life takes priority - sometimes.
Perhaps another descendant of John and Mary might be interested enough to participate?
FamilyFinder test from FamilyTreeDNA or the Ancestry DNA test, but in either case, please upload your file to GEDMatch.
Bear in mind that we still have not definitively proven that Robert DAW in California, born Michigan and father of Mark Walton DAW (b. 1892 Oakland) is one and the same as Robert Henry DAW, son of Isaac Friend DAW who emigrated to Michigan (see prior blog post).
So ideally, descendants of any/all of those mentioned very very welcome to see what we learn about the family relationships from their DNA.

Henderson brick wall
One of my reasons for venturing into DNA testing for genealogy back in 2007 was to break through several brick walls.
Yes, there have been some successes, many intriguing finds, and a lot of new correspondents to share with.
No, I still have no more idea about where Archibald HENDERSON, or Amelia MILLAR for that matter, came from.
Here's the current state of play of mapped chromosome segments inherited/shared by the tested participants, along with those where their matches also match each other forming a triangulated group. The caveat however is that we do NOT know the segments are from the HENDERSON side of the ancestral couples shown, and for those marked as ... anc., the link can be back up either side of the couple, somewhere, somewhen.
In theory, one day a WOW moment will arrive when one of these matches holds the key in their trees and dna to break through that wall.
This picture, and any subsequent updates to it, may be found on both:
The inheritance of atDNA is such that even siblings can show up different segments, and thus more matches, to add into the mix to triangulate.
