THE Irish patronymic of this family is Ua-Coiteoir or O'Coiteoir ("coiteoir:" Irish, a cottager, a boat-builder). In Gibson's History of Cork, this family is stated to be of Danish origin. The name "Cotter," also spelled "Kotter," is common through Denmark and Northern Europe; and, so far as this family was concerned, was in Ireland anciently written "MacCottyr," "MacCotter," and "McCottir." Sometimes the name was in Irish written McCoithir, as well as MacCoithir. The head of the family in the Commonwealth period was William, son of Edmond Cotter, of Coppingerstown Castle, near Midleton, in the co. Cork. That William forfeited his Estates under attainder, consequent on his taking part in the Irish War of 1641. It would appear (see p. 274 of our "Irish Landed Gentry") that, for the same cause, William Catter, of Gearigh, in the barony of Imokilly, co. Cork, then also forfeited his Estates: which inclines us to believe that the two Williams were identical; as there is no other William Catter or Cotter mentioned in the List of the "Forfeiting Proprietors in Ireland, under the Cromwellian Settlement."
Edmond Cotter (son of Garrett Cottir, of Innismore; son of William Cottyr, of Innismore, co. Cork; son of William Cottyr, temp. King Edward IV.), the kinsman and contemporary of the above mentioned William Cotter, of Coppingerstown Castle, was the ancestor of this branch of the family. That Edmond Cotter held considerable property, chiefly Anngrove, which was his principal residence, and situate near Carrigtwohill; he also had property in Innismore, where he held a great part of the site of Queenstown (or "The Cove of Cork"), and land in other districts. While, however, the said Edmond was possessed of considerable wealth, it appears by his Will, that he held his Estates for the most part subject to head rents.

The prefix Ua or O' of this "Cotter" family clearly shows that it is of Irish extraction; for, while some Danish and other foreign families that settled in Ireland assumed the prefix Mac, they never ventured to assume the prefix O'.
