Riley -- an upbeat, friendly Irish surname name -- is red hot for girls (though still going strong for boys). Currently, around five-thousand girls are named Riley each year! It's now Number 47 for girls--not to mention Rylee listed at 109, Ryleigh at 184, ad infinitum. Riley is one of the few contemporary androgynous names that did not lose its masculine power when it became popular for girls.
Newsperson Norah O'Donnell has a daughter named Riley Norah.
