An early mention of this name in Annan is the basis for including the name among allied and dependent families of the Maxwells. Roger Pacok made a gift of six pennies annually in Annan in the 13th Century.
Black lists many other mentions of the name in other parts of Scotland. For example, Pecoc was the name of a Domesday tenant in 1086; Andreas Pacok was presbyter and notary public in the diocese of St. Andrew’s, 1311-21; and the name appears often in the parish register of Dunfermline, 1561-1700. The name is also found in Edinburgh from 1598 as Pacok and Paecok. In some parts of Scotland the name is said to have been corrupted to Paik.
