(French) feminine form of Michel, the French form of Michael. This name is now also used extensively in the English-speaking world. It was popular in the 1970s and 80s, possibly influenced in part by a Beatles song with this name as its title (1966).
English: patronymic from the personal name Robert. This surname is very frequent in Wales and west central England. It is also occasionally borne by Jews, presumably as an Americanized form of a like-sounding Jewish surname.
