(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: nickname for someone with gray hair or a gray beard, from Old English græg ‘gray’. In Scotland and Ireland it has been used as a translation of various Gaelic surnames derived from riabhach ‘brindled’, ‘gray’ (see Reavey). In North America this name has assimilated names with similar meaning from other European languages.
