Would you add known daughter Gwellian of Llewelyn ap Gruffudd and his wife Eleanor, dau. of Simon de Montfort? In Cawley's Medieval Genealogy forum there is a reference from the 'Continuator of Florence of Worcester' that Llewelyn married Eleanor de Montfort and that they had a child Gwenllian who became a nun at Sempringham. Thanks for helping out. Linda M. (alcott-171)
