Re: Rhys Ap Thomas/Katherine Howard, NOT!
You raise some interesting points regarding Edmund's possible descent from this powerful Welsh family. However I think that many genealogists do take the view of Jacobus, rightly or wrongly.
I have not looked into the ancestry of Edmund much since my last post here but rather at his descendants, but I am still interested in learning more about Edmund's roots.
I'll look forward to any future comments you have to make regarding this subject.
