i am also a descendant of T.S. Sorel, over Brentano, Hake, Adelmann.
The Tasmanian William is not a brother of him. "Our" Sorels esp. the grandfather of Thomas emigrated from a little town in the Normandy (Fresnes)to England. T's father and uncle were merchants of silk etc. This - long not - known fact, was found ca. 2 years ago. I have obviously all descendants of him and many notices about the d'Averton. And one thes descendants is - i am quite sure: Stephanie Hohenbruck. Dear Stephanie my adress has your uncle Truman Donoho !
