Need help with name!

Baby girl is due in 6 weeks and I still don't have a name for her!! I considered naming her Poppie, after my great grandpa that was the best man in the world...Elliana was our original name for her, but I started to dislike it. Her nickname would obviously be Ellie, and I just thought it'd be too childish when she gets older. I thought of Madison to keep up tradition in my immediate family for naming their girl with an M. This will unfortunately be our only daughter as I don't think my body can go through another pregnancy. Need help!!
