The name is of Gaelic origin and was originally formatted as Muirgheal (muir sea/ gheal bright) in Irish and Muireall in Scottish Gaelic. Various formats have long been evident in Breton, Irish, and Scottish Gaelic languages. The name was very common in medieval England, typically formatted as Merial, and unusual for a name of Celtic origin remained common after the Norman Conquest although rare from about 1300. Remaining common in Scotland as Muriel, the name in this form was introduced back into England in the mid-19th century, facilitated by Dinah Craik's 1856 novel John Halifax, Gentleman whose title character's daughter is named Muriel; born in 1802 Muriel is said to be named "after the rather peculiar name of John's mother." Usage of Muriel peaked in the early 1920s and has subsequently declined.
