St.Clair Family of Orkney


previous  Eighth Generation  Next

11. Sir William SINCLAIR 5 (Henri10, Henri9, William8, Henri7, Henri3, William 'The Seemly'2, Walderne1) died in 1297.6

Amicia, 'widow' of William de St. Clair had a two year protection from Edward I on 7 April 1299. It is safe to assume that William was deceased by this time.

St Clair's states that the best theory of this William's parentage is that he was the 2nd son of Robert de Saint Clair (p. 279). The Scots Peerage also follows this, however under Niven Sinclair's genealogy he was the son of Henri de St. Clair and Margaret, daughter of the Earl of Mar. I have followed Niven's genealogical research on this matter.
