What's in a name?

I recently saw a television program about the way in which different generations of royal children have been raised. Recently, it was announced that the Duke and Duchess of Cambridge (William and Kate to most people) are expecting a second child. This made me speculate on what the first name of the child might be. Any royal baby may have many names, but I am really only thinking about the name which will be in common use. If the baby is a girl, Will it be time for another Elizabeth? Royal names often repeat earlier names used in the family, but I don't expect the child to be called "Diana". What if it is a second son? I don't expect Charles or Edward for example, to be selected. Perhaps "Phillip", after his great-grandfather. It would be a nice tribute to the Scotts if he were to receive a Scottish name, "Gavin" and "Hamish" would be going to far. "Alistair" is a good name, but not linked to the royal family. "Andrew" seems to be a possibility. One might think that such modern parents as William and Kate could choose any name they liked, but they are a wise couple and will probably conform to tradition.
