Sloane is a sleek, sophisticated surname name that has gradually morphed over to the girl's side. It entered the Top 1000 (at the very bottom of the baby names list) in 2008, and resides at Number 370 in the 2014 list. Sloane is definitely a name that's going to continue to rise. Spelled without the final 'e', Sloan joined Sloane in the Top 1000 for the first time in 2011.
Sloane has been the name of girlfriend characters in Ferris Bueller's Day Off and Entourage; and is currently the character played by Olivia Munn on The Newsroom. Sloane Crosley is a bestselling author, and comedian Rob Corddry named his daughter Sloane Sullivan.
The association with London's Sloane Square and the upscale clique of Sloane Rangers, who have included Princesses Di and Kate, gives it some extra panache.
