I like
Mabel. It's sweet but also really sensible and has a lot of quirk to it. I far prefer
Mabel to
Maybelle, which puts me too much in mind of
Maybelline.
I'm actually surprised
Mabel didn't enjoy more popularity when they named the baby that in Mad About You. And it seems very hipster-friendly. I think it has great potential to become more popular, or at least get on the charts again. I don't know of a single
Mabel.
