I'm having twin girls and we decided on naming one of them Braylynn as well, but I'm having trouble with the middle name for her.
It's you who has to like it. She might tell you if it is getting her teased at school, the "bray" syllable (like donkey bray), or "bra," but if she knows the same set of kids from when she is little, they will be used to it by the time they get to the teasing stage and won't think of those.
