Hi Stephen,
I think it is a well known fact that Edward III was 'father of the nation' - just about everybody is descended from him if they could just prove it!
I've read Anya Seton's book too, although that is a novel based on fact whereas Alison Weir's book is a biography, but they are both extremely interesting, especially to me because I live just down the road from Kathryn's home, Kettlethorpe Hall so I have the local as well as the family interest.
Paul and I have exchanged p.m.'s - he has a lot of information on William's children.
I'm going away for a couple of days now so forgive me if I don't respond to any further messages on the subject for a few days.
Jill
