Thanks for your reply. I believe I am correct that Horace is a descendent of Aubrey who married a de Roucy which is the line I'm actually more interested in. There dosen't seem to be a forum for the de Roucy's. I am trying to link a Belgium to England imm. Lodovicus Rosaeus who dedicated his med. thesis to Edward and Horace. His denization paper states his last name as ROWZEE. He apparently was intimatly acquainted with the de Vere's and so there may be an ancestral connection. Any thoughts appreciated.
