Hyphen or no hyphen?

This is our 3rd and final baby, our first and only girl.

All of our kids are named after someone. Our first has my dads middle name who passed away. Our second shares a middle name with my husband. So naturally our 3rd had to be named after family too.

Her first name will be Madilyn. Me and my husband both had very close bonds with our grandmothers. His passed away. Mine is still here, she’s very active in my life and basically been my mom since I was 14. We decided to give our daughter both of their middle names. We couldn’t make each other choose between the two. Anyways lol after probably an unneeded backstory, not sure if we should hyphenate or not? I know it’s not a big deal but I can’t decide
