Names from your list that I like/love:
Juliet, Vivienne, Lillian, Evangeline (nn. Eve/Eva), Elena (prettier than Helena and the correct spelling of the rather yooooonique Alayna), Gabrielle (though I prefer Gabriella), Fionnuala (nn Fi), Isabelle (and this spelling only), Carly (only as a nn for Carlotta though), Luciana, Jonah, Asher, Gabriel, Ryan, Elijah (nn Eli), Ezra, Frederick (nn Freddie) and Zachary (nn Zac).
Names from your list that I strongly dislike / would strongly advise against:
Caoimhe, Louisa (too dated), Martha (sounds stodgy), Irena, Margo, Alanis, Clodagh, Dorothy (too granny chic for me), Erin, Edith (dislike as it is very granny chic once again), Eithne, Elaine / Lainie (so dated), Orlaith, Ursula (all that comes to mind is the ugly villain from The Little Mermaid.. I couldn't), Lois, Anneliese (v. dated), Stephanie, Noah (too popular), Frank (an old man's name), Robert (old man's name with ugly sounding nicknames), Shane, Dexter and Finley (My mind goes straight to the fins on a fish when I hear this name, don't know why.... What about Flynn? Love that name).
