Deriving from an English locational surname meaning "white island", Whitney was in rare but regular use for boys in the US until the early 1960s, when actress Whitney Blake popularized it for girls. It received a further big boost on the girls' side in the 1980s, thanks to singer Whitney Houston. Now falling rapidly down the rankings, it could be time to reclaim this one for the boys, if only as a neat way to cool-guy nickname Whit.
