Marrion is a name of French origin, derived from the given name Marion, which means 'sea-born' or 'of the sea'. It is a unisex name, although it is more commonly used for males in some regions. The name has been popular throughout history, with notable figures such as Marrion Davies, an American actress and socialite of the early 20th century, bearing this name.
"Marion was quite popular in the early to mid-20th century, with consistent yearly births from the teens to the fifties. However, there seems to be a decline starting around the late 1950s."
