Cuthbertson
Cuthbertson—This Scottish name is the anglicised form of M'Coubrey (Mac Cúthbréith—the son of St. Cuthbert). The name is derived from St. Cuthbert, Bishop of Lindisfarne, a popular saint amongst the Picts, Gaels and Angles. Its older, and certainly correct form was Mac Giolla-Cuthbhreith. It is also written McCaubry.
