Baby Girl Name

I've had the name Kaylee picked out since before I had my son 4 years ago. His name is Jayden. We found out we're expecting our little princess & I wanted to keep the name going with 6 letters and the letter y included. But now since I've had it in my head since what seems like forever, I'm not so sure. At least not about the middle name. Our grandmothers who we miss greatly were Mary Anne & Veronica Mary. So we would love to do Mary but not sure it flows right. The only reason I am against Marie over Mary is because his mother is Rita Marie (evil MIL) and my mom is Diane Marie. Mary has more meaning to us.
