Clancy, one of the original crossover Irish surname names, is as energetic and appealing as ever — full of moxie, more distinctive than Casey, and also one of the less obvious of the red-headed names.

Irish surnames are hot, and this one can successfully cross the line to work for girls, replacing the outdated Casey. And only a dozen girls were named Clancy in the US in one recent year (along with 27 boys), making it one of those rare Irish names that are both accessible and distinctive, classic and cool. Clancy is a winner for either gender.
