The name Murle is of Scottish origin, derived from the old Scots word 'mur' meaning 'sea'. It was traditionally used as a girl's name but has also been used for boys in some instances. In Scotland, it was once popular among the aristocracy, but its usage has since declined and it is now considered quite rare.
"Murle was a popular name during the early to mid-20th century, with over 280 recorded births between 1913 and 1962. The years with the highest number of Murles were 1923, 1924, and 1947, each with 15 births."
