Meaning and etymology
Behind the Name describes Hailey simply as a "variant of Hayley" and lists the root as the surname Hayley. The parent entry for Hayley was not available in this pass, so the meaning of the underlying surname is left unverified rather than guessed. The sister spelling Haley is documented in the same source: its entry says that spelling "gained some popularity in the United States in 1977, possibly due to the author Alex Haley", and that it "was the most common American spelling from then to 2001, when it was eclipsed by Hailey". Behind the Name lists Hailee, Hailie, Haleigh, Haley, Haylee, Hayleigh, Hayley and Haylie as variants.
