Girl name help

For the life of us my husband and I cannot agree on a girls name. If we have a boy, he will be Kellyn Adam. A girl would be ______ Ann.

Our last name starts with a B, is 10 letters, and sounds like "perfume".

We are considering Sera (Sara) as a tribute to my maiden name, Seraphina. We like it but aren't sold just yet. Other soft contenders are Laura, and Kylie. Generally I would like to stay away from the top 30-50 if I can.
