I thought that it wasn't possible to call a child Princess in the UK as that was part of the royal prerogative.. And I can't imagine why Anyone would think that Meghan would want her child to be called after anything royal, even a trad royal name like Elizabeth or Victoria or Alexandra. It would be pretty odd since they did't even give a royal name to Archie and when he was born, they were still working royals settled in the UK. I would have thought too that very few people give a child the same name as their parent nowadays, except as a second name.. so I would not expect Meghan.. I'd expect a name that they like and then possible Meghan or Diana.
