Whew, I'm relieved. :b
Vivienne Marcheline is gorgeous, though it doesn't necessarily "fit in" with the other kids' names, IMO. I like that the mn honors her mom.
Knox,
Maddox, and
Pax = way too many X's for one family. I guess they wanted an X in each boy's name. Whatever.
Knox Leon on its own isn't bad, though, and I like it best of the 3 boys' names, actually.
