Leaving the British X-Factor boosted names to one made popular through a tv show in America. Leighton was boosted by Leighton Meester who played Blair Waldorf in Gossip Girl, and is now more common for girls in the US (but still more common for boys elsewhere in the world).
Leighton is a variant form of Layton meaning “settlement with a leek garden” in Old English other forms of the name include Lleyton, Leyton and Laetyn (a spelling variant which belongs to one of my mutual friends on Facebook) which are also used for girls (Laetyn was given 5 girls in 2013 and Leyton to 26). But Leighton is the most common with 544 girls receiving the name putting it at 540 in the United States and entered the top 100 in 2009 at an extremely high 674 two years after Gossip Girl aired though it had been rising from 2007 when 53 babies were given the name and in 2008 and was at 213 in 2008. Leighton peaked in 2011 at 527 and also charted for boys in 2010 and 2011 but peaked back in 1946 at 913.
Is Leighton a name best suited for boys or for girls? I think I personally prefer it on a boy as the only Leighton I know is a boy.
