Mr. Baildon who contributed information for the material found in Complete Peerage misinterpreted the meaning of a settlement involving the Fitzwilliam family. As a result, he created a ficticious wife for Sir William Fitzwilliam who married Isabel Deincourt. As far as I can tell, Isabel Deincourt was Sir William's only wife.
