Clyde m
English (esp. U.S.): apparently from the river in south-west Scotland that runs through Glasgow, perhaps by way of a surname derived from the river name. The name is comparatively popular among West Indian and American Blacks; Dunkling points out that geographical names such as Aberdeen and Glasgow were bestowed on slaves in the southern United States. A large number of plantation owners were of Scottish origin. Clyde, unlike other such names, seems to have survived, and even gained some currency among southern Whites. The bank robber Clyde Barrow became something of a cult figure, especially after the film Bonnie and Clyde (1967).
