William of Fordham Branches

The following are the known male branches of the William of Fordham line. For our purposes a branch would begin with the sons of the 1st generation. If there was only one son then we would start with the sons in the 2nd generation and so on. We would like to test at lease one individual from each branch. The red highlighted entries are branches for which we do not have test participants. Of course we will accept any Davenport participants but especially need the non-highlighted branches.

If there are additional branches not listed or other changes need to be made - contact info "at" davenportdna.com
