Fitzwilliam

There are descents from two families here, the Viscounts Fitzwilliam of Ireland and the Earls Fitzwilliam of England. There is no reason to believe these two families share a common origin - though there were a number of contacts between the two families through the centuries, and they often referred to each other as kinsmen.
