The Anglo-Saxon name Isaak comes from the baptismal name Isaac. The surname Isaak referred to the son of Isaac which belongs to the category of patronymic surnames. The name is derived from the Hebrew word "yishaq" meaning "laughter." 1

The first record of the name in ancient Britain was found in the Domesday Book of 1086 where Isac was listed. 2 "This, as a baptismal name, was introduced about the time of the Conquest. One Isac appears as a chief tenant in Domesday Book." 3

"Hundreds of English people bear one or other of these surnames in whose veins there flows not a single drop of Jewish blood." 4

The Hundredorum Rolls of 1273 included: Robert filius Isaac, Lincolnshire; Isaac Judxus (the Jew), Yorkshire; Johannes Isaak, Norfolk; and John Ysac, Oxfordshire. 4

Isaac was prior of Scone from 1154 till 1162, and Magister Isaac was a cleric of St. Andrews, 1201. Ysaac of Brechin was a charter witness there c. 1178-98, and Ysaac de Banevin (Benvie) was one of a jury regarding the Kirketun of Aberbuthenoth, 1205." 7
