The ancient Norman culture that was established in England after the Conquest of 1066 produced the name of Cosom. It was given to a person who was related to someone of note in the area. Further research showed the name was derived from the Old French, cusin, and the Old English, cousin, which means relative. 1

Early Origins of the Cosom family

The surname Cosom was first found in Norfolk and in the southern counties of England, where the first on record appears to be Roger Cusin, listed in the Pipe Rolls in that county in 1166. Robert Cusyn and his wife Joan were landowners in Ellisfield, Hampshire during the Reign of Henry III (1216-1272). Peter Cusin was a sheriff of London in 1273. A Galfridus Cusyn of Hardingham, Norfolk is mentioned in the Subsidy Rolls for that county in 1327. 2

The Yorkshire Poll Tax Rolls of 1379 lists: Johannes Cosyn, tiropour; Ricardus Cosyn; and Alicia Cosyn, 1379. 2

Cosom Spelling Variations

Multitudes of spelling variations are a hallmark of Anglo Norman names. Most of these names evolved in the 11th and 12th century, in the time after the Normans introduced their own Norman French language into a country where Old and Middle English had no spelling rules and the languages of the court were French and Latin. To make matters worse, medieval scribes spelled words according to sound, so names frequently appeared differently in the various documents in which they were recorded. The name was spelled Cousin, Cousins, Cozens, Cossins, Couzins, Cossens, Cosin, Cosyns, Cousens, Couzens, Cossins, Cosin and many more.

Migration of the Cosom family

Because of this political and religious unrest within English society, many people decided to immigrate to the colonies. Families left for Ireland, North America, and Australia in enormous numbers, traveling at high cost in extremely inhospitable conditions. The New World in particular was a desirable destination, but the long voyage caused many to arrive sick and starving. Those who made it, though, were welcomed by opportunities far greater than they had known at home in England. Many of these families went on to make important contributions to the emerging nations of Canada and the United States. Analysis of immigration records indicates that some of the first North American immigrants bore the name Cosom or a variant listed above: John Cosins who settled in Maryland in 1683; Richard Cousin settled in Grenada in 1774; Edward Cousins settled in Maryland in 1774; George Cousins settled in Massachusetts in 1635.
