Meaning and history
Marilynn is a modern spelling variant of Marilyn, a name formed in English from Mary and the suffix or name Lynn. Mary comes from Hebrew Miryam, whose original meaning is uncertain. Lynn derives from a Welsh word meaning “lake” when used independently, but in Marilyn it primarily functions as a name element rather than a literal translation. Notable bearers include American professional golfer Marilynn Smith and American Mohegan leader and public official Marilynn Malerba.
Marilynn rose from #734 to #725 for girls between 1958 and 1959. Its highest annual birth count came in 1947, with 407 births.
