Sibling name to go with ...

What would be a good sibling name to go with Moira? We both really loved the name Moira for our first, but coming up with a name for her baby sister has proven more difficult. Getting close to third trimester, so . . . we need to decide soon!

A few names we've been kicking around, but are not 100% sure on: Arianna, Brielle, Isabelle, Laura, Leanna/Liana, Leona, Naomi, Rebecca, Sylvia, Zoe
