The names Collier and Collyer have exited in Ireland since 1305 and are derived from the occupational name. Familes bearing this name formed a Sept along native Gaelic lines and were know as Coileir. The principal settlement areas were in Counties Carlow, Kilkenny and Wexford where the majority of descendants can still be found.

Origen: Normando. The ancestors of the Collier family name lived among the ancient Anglo-Saxon culture of Britain. The surname Collier is derived from the Old English word "col," which means "coal;" as such it is thought to have originally been an occupational name for a burner of charcoal or a gatherer or seller of coal. First found in Lancashire where they were seated from very ancient times, some say well before the Norman Conquest and the arrival of Duke William at Hastings in 1066 A.D.

Variantes: Collier, Collyer, Colier, Colyer, Colyar, Colyear y otros.
