This line of Binghams has been very difficult to trace. When I began my search, no living member of our family that I could find even knew the names James S. Bingham and Lavica Ann Dyches Bingham. By participating in a Family Tree DNA project in May 2004, I got a match with two other participants.
An explanation of the process best comes from that site, which states “The Y-Chromosome is passed from father to son unchanged, except for a mutation about every 500 generations. Testing the y chromosome provides a genetic finger print consisting of 12 or 25 markers. This finger print is then compared against that of other men in the Surname Project by matching the markers. By comparing the fingerprints, or markers you can determine if you are related”. Family Tree DNA currently has over 800 surname projects. To see if there is one for a surname you are interested in, go to this site.
This line begins with James S. Bingham and Lavica Ann Dyches.
