From the experts:
Chelsea is still being used, but it was much more popular a few decades ago--it peaked at Number 15 in 1992. Chelsea first entered the American consciousness in a major way via the character Jane Fonda played in On Golden Pond in 1981 and later of course was frequently in the headlines when Chelsea Clinton (whose name was inspired by the lyric of a the Joni-Mitchell-Judy Collins song "Chelsea Morning") became First Daughter.
