Baby names

Melissa

Currently pregnant with my second child. We named our first Emersyn. We won’t be finding out the gender, we already have a boy name but not a girl name. We both like Madison but would it be okay to spell it like Madisyn so that it kind of matches Emersyn or it is that too much?

I also like the name Evelyn but I didn’t know if the E names clash together to much.

Let me know your thoughts!
