Cumyns History, Family Crest & Coats of Arms
It is generally believed that this name comes from a Breton personal name, derived from element "cam," meaning "bent," or "crooked;" or perhaps from the herb called "cummin" (cumin).
Or the name may have come from the place name Comines, in Northern France, bordering the Belgium border. Regarding this latter scenario, multiple sources agree with this postulation, but all include wording similar to "there is no positive evidence in favor of this view."   
Early Origins of the Cumyns family
The surname Cumyns was first found in Norfolk, Lincolnshire, and Yorkshire in England, in the 12th and 13th centuries. Robert of Comyn (Comines,) (died 1069) was a noble who accompanied William the Conqueror and was made Earl of Northumberland. "He so commended himself to the king by his military skill that he was chosen at the end of 1068 for the difficult task of reducing the north of England to obedience. William I conferred on him the earldom of Northumberland, vacant by the flight of Gospatric. Comin was the founder of the family of Comyn, many of whom played an important part in the history of Scotland." 
"The first of the name connected with Scotland is Willelmus Comyn, a churchman, chancellor to David I. He was promoted to the bishopric of Durham by the Empress Matilda, but had many controversies with his clergy. Later he was poisoned by some of their number who mixed poison with the wine of the Sacrament and give it to him to drink. Richard Cumyn, second of the name in Scotland, made a gift of the church of Lyntun-ruderic (Linton-Roderick) to the Abbey of Kelso for the weal of the souls of Earl Henry (d. 1152) and his own son, John. He also witnessed charters by William the Lion after 1165 (REM., I, 2). By his marriage with Hextilda, granddaughter of Donald Bane, king of Scots, he had a son, William, who became chancellor and great justiciary of Scotland. William married Marjory, daughter and heiress of Fergus, the last Celtic earl of Buchan between 1211-1224, and in right of his wife became earl of Buchan. " 
John Comyn (d. 1212), was Archbishop of Dublin and was in his early life a trusted official and chaplain of Henry II.
Later, John Comyn (Cumyn) (c. 1215-1275) was Lord of Badenoch in Scotland and justiciar of Galloway in 1258. He founded and started the construction of Blair Castle with a tower in 1269. He was nephew of Alexander Comyn, Earl of Buchan, Constable of Scotland, and of Walter Comyn, Earl of Mentieth. 
Alexander Comyn, 2nd Earl of Buchan (d. 1289), was Constable of Scotland, "the son of William Comyn, Earl of Buchan, the founder of Deer Abbey, and of Marjory, his second wife, who brought the title into the Comyn family. " 
John Comyn the Elder (d. 1300?), of Badenoch, was 'claimant to the Scottish throne,' and was the second son of John Comyn, Justiciar of Galloway. His lordship of Badenoch came from his uncle, Walter Comyn, Earl of Menteith. 
His son, John Comyn the younger (d. 1306), of Badenoch, surnamed The Red, was one of the competitors for the crown of Scotland in 1291.

Migration of the Cumyns family to Ireland
Some of the Cumyns family moved to Ireland, but this topic is not covered in this excerpt.
Migration of the Cumyns family
Many settled along the east coast of what would become the United States and Canada. As the American War of Independence broke out, those who remained loyal to the crown went north to Canada as United Empire Loyalists. The ancestors of all of these hardy Dalriadan-Scottish settlers began to recover their collective history in the 20th century with the advent of the vibrant culture fostered by highland games and Clan societies in North America. Highland games, clan societies, and other organizations generated much renewed interest in Scottish heritage in the 20th century. The Cumyns were among the earliest of the Scottish settlers as immigration passenger lists have shown: Elizabeth Comyngs, who settled in Plymouth, MA in 1620; George Cumming, who came to New Jersey in 1685; William Cumming, who arrived in Annapolis, MD in 1717.
