Surname Name Meaning, Origin, and Etymology
This is a patronymic or baptismal surname meaning “the son of Isaac”, an ancient Hebrew personal (first name), also spelled Isaak, Yitzhak, or Yitzcock, born by one of the three patriarchs of the Bible, living in Canaan (ancient Near East or the Levant), son of Abraham, whose story is told in the book of Genesis, loosely translating to “laughing” or “laughter”. The Greek translators of the Old Testament changed Yitschak to Isaak, it was later it was Romanized to Isaac. Tradition or legend states that when Abraham and his wife gave birth to Isaac at an old age, they laughed with joy, but another interpretation is that God laughed, meaning God smiled upon him. The name is frequent in Wales and is a popular Welsh surname because it was popular among nonconformists in the seventeenth through nineteenth centuries.

History, Genealogy, and Ancestry
George Fraser Black’s 1946 book The Surnames of Scotland, states the following in regard to this last name:  “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. Isaac, son of Samuel, was one of the witnesses to the gift by Walter, son of Alan, to the monks of Scon, c. 1214 , and Isaac, burgess of Aberbrothoc, witnessed a charter by Matilda, countess of Anegus c. 1242—43. Isaac of Scone witnessed a quit-claim of the land of Drumkarauch in 1260, and Gillandes Macysac witnessed a charter in favor of the priory of Beauly in 1231. Sir Thomas Isaac was a witness in Edinburgh in 1358, Andrew Isak of Scotland had a safe conduct into England in 1405, John Ysaac had a safe conduct to pass to France in 1447, and Thomas Esok was canon of a church of Argyll in 1448. Thomas Esak was messenger-at-arms for Dunbartane in 1569, Jonet Isack was a witch in Kilwinning, 1662, and in 1671 a charge of usury was brought against Robert Isack in Kirkcaldy. A certain squire named Thomas Isaac married Matilda, daughter of King Robert Bruce. Concerning this singular mesalliance the late eminent genealogist, Mr. Alexander Sinclair, writes: ‘The name was not so low as it seemed. It was disguised into Ysac, Ysaac, and de Ysaac to make it appear noble This individual not long after had his name borne by gentry bearing the same name with coat armour, in the south of England. In Devonshire there were Isaacs of Buriat, temp. Henry III, who bore Sable, a bend or, on a canton argent a leopard’s face gules. In 1460 there was also John Isaac of Bekesbourne, sheriff of Kent, who had the same arms, but the leopard’s face or. Probably Thomas, the lucky adventurer was connected with one of these old families. Isaac, clericus, was bailie and burgess of Aberdeen in 1332. Eizack 1694”.
