This image of this distinguished Anglo-Scottish surname, drawn from the French place name of the ancient castle of Saint Foi de Montgomery, is rapidly shifting from fusty and formal to cool. And dashing short form Monty (or Monte) nudges it to cute.
Best-known bearer of the name is beautiful-but-tortured midcentury actor Montgomery Clift. Roger de Montgomery was a Norman nobleman who was made Earl of Arundel after he invaded England in 1066 and Sir Bernard Montgomery was a noted army commander in World War II. Montgomery is also the proper first name of Star Trek's engineer Scotty and, less flatteringly, the middle name of The Simpsons' evil Mr. Burns.
