Izaac History, Family Crest & Coats of Arms

Izaac is an ancient Anglo-Saxon name that is derived from the baptismal name Isaac. The surname Izaac 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]

Early Origins of the Izaac family

The surname Izaac was first found in the Domesday Book of 1086. From this early entry, the name in both forename and surname forms became widespread with many early spellings. Willelmus (William) filius Ysac was listed in the Curia Regis Rolls for Essex in 1206; Henry Isaac was found in the Subsidy Rolls for Worcester in 1275, and Walter Isak in the Subsidy Rolls for Somerset in 1327. [5] [6]

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

In Scotland, "the name was not uncommon among ecclesiastics in the twelfth and thirteenth centuries. 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]

Migration of the Izaac family

In an attempt to escape the chaos experienced in England, many English families boarded overcrowded and diseased ships sailing for the shores of North America and other British colonies. Those families hardy enough, and lucky enough, to make the passage intact were rewarded with land and a social environment less prone to religious and political persecution. Many of these families became important contributors to the young colonies in which they settled. Early immigration and passenger lists have documented some of the first Izaacs to arrive on North American shores: Robert and Lucy Isaac settled in Savannah in 1821; William Isaac settled in Grenada in 1776; Rebecca Isaac settled in New England in 1634; Jonas, William, Terry, Phillip Isaac all arrived in Philadelphia between 1840 and 1860..
