Kool (surname)
Kool is a Dutch patronymic surname. Kool is an archaic short form of the given name Nicolaas. Since "kool" means both "cabbage" and "coal" in modern Dutch, for some families the name could conceivably have originated as a metonymic occupational surname, referring to a cabbage farmer or seller, or coal worker.
