Meaning and history
From a Scottish surname meaning “from the mouth of the Roe,” referring to the River Roe in Northern Ireland, Monroe became known through figures such as U.S. president James Monroe (1758–1831) and actress Marilyn Monroe (1926–1962). As a given name in America, it was used mostly for boys until around 2009, after which it began rising for girls; singer Mariah Carey’s use of it for her daughter, born in 2011, likely helped speed that trend.
