The Scottish surname Taggart, also found in northern Ireland, is an anglicized form of the Gaelic name Mac an t-Sagairt meaning “son of the priest,” from sagart ‘priest’. Marriage by members of the clergy was prohibited after the 12th century, but was frequently practiced nevertheless. The name is first recorded in Scotland in 1215. The earliest record of the name in the New World is in 1723 when Hugh Taggart is recorded in New England. Today there are approximately 9,000 bearers of the surname Taggart living in the United States.
