I love it Both the boy's and girl's. Boy's because it's tradition, and I think it'd be great growing up knowing you're the 5th in your family with that name, it gives you some history. And I like how you've picked the girl's name - def go with something you love (Paiton) and I like the two grandmother's being included. And they sound nice

Congratulations on your pregnancy, hope it's a happy & healthy one for you!
