First, there was the unisex Riley, inspired by the Irish surname O'Reilly that began its rise to fame in the 1990s. Then the alternatives started rolling in, and one of them was Rylie—same sound, different spelling. It’s a cute name, and with its “y” and “ie” ending, it’s more suitable for girls than boys. O'Reilly means "descendant of Raghallach," a name whose exact meaning is tricky to uncover. Want even more choices from this Irish family? Try Ryleigh, Rylee, or Rylee, all for girls.
