I sort of doubt that a boy would be named Charles, especially not as a first name. I'm not sure about godparents. But perhaps they won't be restricted this time under the rules of the Church of England. As I believe in the Church of England only godparents of Protestant or Catholic faith are chosen. That's why Archie's godparents would not be any of Meghan's friends who are Jewish (Misha, Jessica, Lindsay) or Jehovah's Witness (Serena).
I wonder with this new baby's christening happening in the U.S., whether M&H would have more leeway regarding who they choose. If so, I'd bet Oprah, Amal Clooney, Ellen, James Corden, and possibly Gloria Steinem might be in the running. Maybe Harry's good polo friend, Nacho Figueras, and possibly Tristan Harris (of The Social Dilemma), et al. The Sussexes have made some good new friends since they left Great Britain. And they are now living closer to some of their old friends.
Archie's godparents were never officially revealed, but I believe on Harry's side it's Tiggy Legge-Bourke, Charlie van Straubenzee, and Mark Dyer. On Meghan's side, I would guess Benita Litt, Genevieve Hillis, and Markus Anderson.
Hmmm, I don't think they would do that to a daughter. It's more likely combining both of their mother's names and honoring either Meghan's maternal grandmother in some respect too, such as Doriana Jeanette, or something completely unexpected in the way they chose Archie's name.
The fact that they chose 'Harrison' made me think they were checking the name suggestion thread here where a poster whose name I don't remember had the brilliant idea of 'Harrison' as a possibility, and M&H were on the same page. LOL
