Deciding Baby Name Spelling

Hope

Okay, I have a dilemma. We want to name our baby girl Marilyn BUT we must keep Marie in the name. So, I thought about spelling it Marie-Lynn. Do y'all think this will be an overly mispronounced name and I shouldn't do it or stick with it?

Or what are some suggestions?

I don't want Marie as her name or middle name though either because I find it's way over used.
