Re: Good names for my Twin Girls?
I love the AoGG reference, but I think it's going to be mispronounced very often. Your daughter will always have to be correcting people.
Also, Sheridan is still so much of a surname to me, I'd find it odd as a given name.
Having said that, I love both Jane and Therese, and if it were me, I'd reverse them:
Jane Avonlea & Therese Sheridan
