My earlier 20-marker Y-DNA test results were disappointing - I found no close matches in the DNA Ancestry or YSearch databases, but there were no apparent descendants of Robert Seaver, the 1634 immigrant to New England, in any of the databases.
When I clicked the "Find others that match your DNA" link on my GeneTree Marker page, I saw this page:
There are two tabs on that page - "Y-DNA Match Search" and "Surname Match Search." On the "Y-DNA Match Search" page, I could choose between Exact, 85% or 70% Matches, so I chose 85%, and clicked on "Search." There were 166 entries in the GeneTree database that matched 85% or more of my markers. Here are the first two pages:
Well, that's encouraging, to say the least! Even some "Exact" matches, but they are limited to no more than 13 markers in common. And none of them are named Seaver.
There are only the two "Seaver" entries, but there are some on the list with fairly close spelling or pronunciation - like "Severe" and "Sevy" - but only the two "Seaver" matches have better than an 81% match.
I have the Charles Edward Seaver, that married Mary Main, in my Seaver database - he is a 5th great-grandson of Robert Seaver (1608-1683) and a 3rd great-grandson of Joseph Seaver (1672-1754). The #1 on the pedigree chart above is an 8th great-grandson of Robert and a 6th great-grandson of Joseph. My guess is that #1 on the chart is the father or grandfather of the person who submitted his DNA for testing.
