Thoughts on this girl name?

Jocelyn might work. Then when your child grows out of being joy they have somewhere to go. I think joy marilyn works best. I don't think a middle and a first name that are both like real things usually sounds good such as joy and rosemary. I might just name your kid Jocelyn and call her joy yourself but not ask other people to. I know kids names hope and joy and miracle and stuff like that and they all hate it. I might reconsider.
