I like them all, the boys names more than the girls. I think they all fit together okay but would almost bebetter as two sibsets:
Cosette and Bennet (fit in well with current trends, soft, more likely to be immediately recognized as literary) and
Lorna and
Quincey (unexpected, quirky, more subtle literary theme). Thinking about it, I’m really digging just
Lorna and
Quincey together.
Maybe this is just my own ignorance but I only learned fairly recently that
Lorna Doone was a book. It just makes me think of the cookies lol.
