Doig is a surname originating from Scotland. This is an anglicised form of the Scottish Gaelic name Mac Gille Doig - a compound of the elements "mac" meaning "son of", "gille", a servant, plus the personal name Doig, a short form of Cadog.^[1][2] The name therefore translates as "son of St. Cadog's servant". In Scotland, the name appears most often on record in places where St Cadog was commemorated. The name was first recorded in the latter half of the 14th century as "Dog'. The spelling 'Doig' appears in the 17th century. Other modern variants of the name are Doag, Doeg, Doak, and Doidge. ^[2]
