Well with Archie there was so much considered speculation on here and it ended up being a typical top 20 kind of name that wasn't very Royal and worked in America. So the same here. Nothing traditional or formal, nothing cleverly put together to mean anything or flow beautifully or to impress naming experts, just a simple trendy name they both happen to like. And if it's a girl then Diana is the middle name. They are incredibly publicity hungry and it's a good attention grabber, plus it's a bit of a snub to the traditional royals. Not Diana as a first name- it's not trendy at all. I would quite like to see the baby called Brianna or Aubree for a girl just for fun. For a boy Arlo?
