Suggestions for baby girl names

Both my husband and I like the idea of honoring our lost parents when we name our children. We are due to have our baby girl May 3rd and want to use my Mom's name, Rebecca, as her middle name. We'd use it as a first name, but I just can't bring myself to call her by my Mom's name. Anyway we are having a hard time coming up with first names that go well with Rebecca as a middle name. Suggestions??
