The progenitor of the Clan Sutherland was also the progenitor of the Clan Murray who was a Flemish nobleman by the name of Freskin the son or possibly grandson of Ollec. Freskin's grandson was Hugh de Moravia who was granted lands in Sutherland and was known as Lord de Sudrland. Hugh's brother, William was progenitor of the Clan Murray. Hugh's eldest son (also called William) was William de Moravia, 1st Earl of Sutherland. The place name and clan name of "Sutherland" came from it being the land to the 'south' of the Norse Earldom of Orkney and Caithness. Although the senior line of chiefs who were Earls of Sutherland were known by the surname 'de Moravia', the younger sons of the family would take the surname 'Sutherland', creating the cadet branches of the Clan Sutherland.
