When DNA for genealogy began just a few years ago, the main tests were y-DNA for males only and mt-DNA for males and females testing the only the direct female line. Since then, study of lots of samples has yielded a third test, FTDNA calls theirs Family Finder, which yields results of all ancestors back as far as five generations. Thus a Whidden female married to a Graham, whose son fathered a son with a local girl and the descendants test shows up in my FF results, thus solving a 200 year old mystery. If you have any other questions, I'd be glad to help. Four Whiddens have had their DNA done, thus confirming a connection back to Whidden/1662/NH. Now if only I could get that kind of result with my Finnish research.
