I love thinking of names, here's my guesses/hopes:
Alice Christina Sibylla Josephine
Alice - Victoria's and princess Sibylla's middle name and Silvia's mother's name, Christina - classic royal name, Sibylla - princess Sibylla, Josephine - queen Josephine, sounds good with the other names.
I would like Sibylla as the first name, but it's also a Swedish fast food restaurant, so maybe not ... I'd also like Hedvig, Eleonora, Margareta.
Edmund Oscar Carl Leopold
Edmund - what Victoria's grandfather prince Gustaf Adolf was called by family, Oscar - like the two kings, Carl - of course, Leopold - my wildcard just because I like it, from Prince Leopold, Victoria's great-great-grandfather.
(Please just name him anything else than a double name with Gustaf and Carl, we've had enough of those.)
