About Henri de Saint-Clair


Henry de St. Clair (fl.1180) [granted Carfra, Lauderdale and Herdmanston, before 1189]

	Alan [granted Langild, Lauderdale, before 1196] m. Matilda, dau. of Alexander de Windsoure of Morland	 
	Ada m. Petrus de Haga	 	 	 	 	 	 

The only St. Clairs in England who would have had foreknowledge of William the Lion attending Henry II's court on his way back to Scotland would have been the sons and grandsons of Hugh de St. Clair. Henry de St. Clair, who founded the Herdmanston St. Clair line, may well have been one of his grandsons. However, it cannot as yet be confirmed that William de St. Clair, who was granted Rosslyn in 1180 according to Nisbet, was his brother, but it seems very likely.

Three lines of descent originated with William, earl of Orkney, earl of Caithness, Lord St. Clair, and lord of Rosslyn, who died in 1480. The lords St. Clair descended from William (the Waster), his only son from his first marriage, the earls of Caithness descended from William, his first son from his second marriage, and the lords of Rosslyn descended from Sir Oliver, the latter William's brother.

In 1620, Sir Oliver's great great grandson, William Sinclair, settled in Ireland with his second wife and two children, George and William Sinclair, leaving his ancestors' inheritance in Scotland to his eldest son, Sir William St. Clair of Pentland.
