I'm thinking
Mary Diana Catherine Elizabeth for a girl. I thought maybe
James for a boy but she has a brother named
James, so maybe
George William Charles Philip? I bet they have a lot of rules for the naming of a royal baby that will likely be a future monarch so I really have no idea. Maybe they give them a jar of names to pick out of.
I'm hoping they pick a royal name from farther back in the tree, like Matilda/Maud,
Mary,
Richard,
George,
John, or
Eleanor. Or
Harold!
Edith! Oh man can you imagine. I hope they have twins named
Harold and
Edith. Best royal names ever.
