The Irish name selection on this site is totally bogus. Apparently Cody, Jacqui, and Kelsi are Engish & Irish feminine names. Those are not even Hiberno-English names.
For instance, you would often see names like Cailin, or Erin in American-Irish (they mean girl, and Ireland respectively) names, but these would be incredibly uncommon in Ireland itself.
