Many years later, we finally had Lyn do a DNA test with AncestryDNA.I now have a project to understand ThruLines. Bob pointed out in another email that this has other implications for privacy of the living. Eg adoptions. In fact we know of someone (not renated) who discovered a half sister through Ancestry. As Elizabeth Selwyn shows, you do not have to get your DNA tested for information about you to be available. The DNA tests link family trees. And the DA and Family tree databases are steadily expanding.
The “ThruLines" facility of Ancestry had a number of matches with Elizabeth Selwyn, but absolutely zero for Thomas Rowley.
Why, why, why?
On Lyn’s “Group” facility, there were a number of matches that related to a single forbear - without a name.
I called this group, the mystery match.
One of the researchers of this mystery group gave me the answer by having in his tree Simeon Lord as a forbear!
I rearranged Lyn’s tree with Ancestry to have Simeon Lord as Eliza’s biological father.The result was, quite a number of positive matches now appeared - Simeon as the biological father.
