Given the reported enmity between Queen Elizabeth and Diana, I just don't see the queen allowing the princess to have Diana as any of her names. Out of respect for the queen, I think William and Catherine will comply with her wishes. "Mary" seems a likely candidate to me, not necessarily as a first name, but then George is a fairly traditional name so I wont be surprised if they call her Mary.
She looks like a Rose Frances Mary Alexandra to me.
Unabashed Anglophile that I am, I watched the live feed yesterday morning and caught them leaving the hospital. While sipping my English Breakfast tea
My favorite moment was when Catherine started down the steps and William took her hand to steady her. That moment - and when he kissed George's cheek - got my sentimental tears flowing and reminded me how much his mother's son he is.
Congratulations to the Duke and Duchess and Prince George (and Lupo!) on their beautiful addition to the family. And welcome to the world, little Princess!
