From an Irish surname, derived from the Irish byname
Leannán meaning "lover". The surname was borne by musician and Beatle member John Lennon (1940-1980), and it may be used as a given name in his honour. In America it is now more common as a feminine name, possibly inspired in part by the singer Lennon Stella (1999-), who began appearing on the television series
Nashville in 2012
