I'm not sure, myself, about a sister of Robert de Beauchamp being thewife of Richard fitz Turolf - the Beauchamp sister seems to belong to thegeneration of Richard's grandchildren, that is, as the wife of RichardfitzWilliam, Sheriff of Cornwall 1207, younger brother of RobertfitzWilliam (3). That would make her Matilda fizIve, sister of Robert deBeauchamp (c.1130-c.1190). A wife for a Domesday tenant like Richard fitzTurolf would seem to require her to be a sister of the progenitor of theBeauchamps of Hatch, Robert fitz Ivo, Constable of Robert, Count ofMortain.

Note: I have a much earlier Robert de Beauchamp of Hatch in my ancestry,son of Robert FitzIvo. Ivor is probably referring to the RobertBeauchamp of Hatch who was b. c 1191, which is too late to be the brother.
