Notes for Basilia
K-R reports that J-N Mathieu in "Les Comptes de Dammartin" in Paris et Ile-de-Francs, Memoires, t. 47 1996 has suggested that Basilia was the sister of Hamo de St Clare, Damo holding of Eudo Dapifer.
Another theory is that Basilia was the dau. of Philip de Braose and Aanor de Totnes; no evidence found yet.
