Thank you for posting this very interesting information.
Could you please tell me where you got the information you do have so that I can work on confirming it?I have some information from a Portuguese source on Arnaldo de Baião, and am trying to source other material.
Thanks in advance for your help. Kathy M
I am descended both through Sancha Viegas de Baiao as well as King Afonso VI through Mem Fernandes Antas.
