WOW! I am truly impressed. My method is much less high tech. I am mostly looking for "grandmothers" born in the late 1700s and early 1800s with probable colonial roots. I have been copying each possible match with that surname (in New England) into a text file and comparing them until I find 4 or 5 for the same family. Then I can concentrate on that family to find my lost daughter.
Hats off to you!
