I still firmly like Audrey Louise. I think Love is a little cutesy and yes, it does turn her name into a political statement of sorts. I understand your hesitations over the internal assonance of Audrey Israel but really, truly don't think it's a problem. It's not a frank rhyme, like Lizzy Israel or something.
I assume you've looked at longer and slightly fresher takes on Ada, like Adeline, Adelaide, Adrienne, Adara or Adela?
Mae is sweet but doesn't seem nearly as meaningful as the others.
Thank you all, it always makes me feel better to read your replies. I don't know how we named two children so effortlessly before this! I'm happy to hear your thoughts, but even having one vote for each helps me to believe we won't be making a mistake with any of the choices, except maybe Love which I agree with.
