Meaning and history
From an English surname derived from place names ultimately based on the Welsh word llyn, meaning “lake,” Lynn was used mainly for boys before the early 20th century but is now more often given to girls. It is also sometimes treated as a short form of Linda or of names ending in lyn or line.
Lynn moved from #900 to #933 for girls between 1995 and 1996. Its highest annual birth count came in 1956, with 7,736 births.
