Either two different people got merged or he actually married both women.
In the beginning this profile started out with an Ens. James Head as the father. I do know I have DNA matches up to John Head Sr and Nancy Ann Sanford. Just trying to sort this out. Any help would be appreciated. I have Ancestry matches of John Head Jr, so far that I am aware of anyway, to his children Nancy R. Trotti , Martha Ann Dickerson (of course it's my 3rd ggrandmother) and Thomas Wollem Head as well as to his sibling Harriet Amanda Rucker..Again any help would be greatly appreciated. Please and thank you.
