Cailín is the Irish word for "girl", and as such is not in use as a personal name in Ireland.

No of course not, to find girls with irish names, you have to come to america! the irish tend to name their daughters after saints, and many 'continental names' were popular(when my cousins, just a few years younger than me, were being born. so i have no irish born cousins named Coleen, Shannon, or Erin, or Caitlin, (only american born ones) -my irish cousins (one Patricia) are Antonia, and Maria, and Grace, 'ethnicly neutral' names like Geraldine, Ann,
there are some brian's and michaels among the boys, but also Bernard, and Damian.

my sister is Deirdre, but that name has not reached national popularity here in US-but Soibhain has!(and its often spelt Shavawn)
one cousin goes by the name Doreen, but its a nickname, not her given name-- and besides, she lives here.
(my son considered Una (with a varient spelling) as name, but instead, my granddaughter is Beatrice)
