I descend from Martha Eltonhead (md. Edwin Conway). I also am interested in how the Eltonheads tie into the kings & queens.
There is information out on the net, from Plantagenet Ancestry by Douglas Richardson, that seems to indicate the Eltonheads descend from a child of Henry II & a mistress. In many circles, this would be recognized as royal descent due to the less than legitamate birth.
I'd love to know any other connections into royalty. A connection won't pay the bills but would be interesting to info to have.
