I don't really have any names I strongly dislike, but there are names I would never choose.
Poppy, Grace, Zoe, Rosie, Ivy, Eve/Evie, Elodie, Eleanor, Isabel/isabella, Summer, Autumn, Sunday, Wednesday, Lyra, Mabel, Kitty.
I like the name Elodie when it's pronounced with a French accent, but when English people say the name it always sounds like they are saying hello to someone named D and dropping the H to me.
Dominic, Hugo, Jude, Benson, Oakley, Teddy, Phoenix, Bear.
