Really meant William Longespee. Just reading about past debates on this William's mother. [Henry II said to acknowledge being his father.]
Through the ancestry/tree of family of James Madison [part of my family tree] various lines come from Henry II and Eleanor of Aquitaine, as well as from William Longespee.
Seeing this, I realized intertwining of lines from "legitimate" offspring and illegitimate offspring of Henry II..
Just curious if DNA testing has been done to CONFIRM that Rosamund Clifford is 100% eliminated as mother of William Longespee?
