Lile is pronounced
Lilly. Which I don't find very interesting really.
Eilidh is pronounced EYE-li. A version of Eilene. Also not my favorite.
Delaney is a last name, and there are so many gorgeous Irish girls names that I'd never use a family name as a fn.
Laoise is okay, but I much much prefer
Saoirse.
Brigh is nice. I like that spelling because its so close to "bright". the meaning isn't that enchanting though. Again, I think there are so many nicer Gaelic names. Also, if your seriously thinking of using them with Irish spellings Please please pronouce them properly, otherwise just anglecise to the sound you want. ie
Leela vs
Lile (
Lilly)
