The English surname Baldwin is of patronymic origin, being derived from a Germanic personal name composed of the elements bald  meaning “bold or brave” and  wine meaning “friend.” It was the personal name of the Crusader who in 1100 became the first Christian king of Jerusalem, and of four more Crusader kings of Jerusalem. It was also borne by Baldwin, Count of Flanders (1172–1205), leader of the Fourth Crusade, who became first Latin Emperor of Constantinople. Among the notable bearers of the surname is John Baldwin (died 1545), judge at the trials of Bishop Fisher, Sir Thomas More, and Anne Boleyn. One Thomas Baldwin was an early settler in the American Colonies, being listed in a "List of the Living in Virginia" compiled on February 16th 1623.
