An old English name, first recorded in Scotland c. 1200 when Philip de Maleuille married Eva, daughter of Walter, son of Sibald. The name is later largely associated with Fife and Angus, although Sibbalds also appear in Lanarkshire and Stirlingshire. The name is thought to derive from a word meaning 'Sea Bold' or 'Victoriously Bold'. The most famous member of this family was the Fife naturalist and historian Sir Robert Sibbald (1641 - 1722).
