If it's a boy it will be Carl-(fill-in-the-blank) ... a girl .... Christina would seem to be a good choice since it's the name of a former Queen of Sweden. I think that other names which may be included are:
Carl-?, Olle Daniel Bertil
Christina Sybilla Louise Silvia (or even Renate which is Queen Silvia's middle name)
Carl-?, Olle Daniel Bertil
Christina Sybilla Louise Silvia (or even Renate which is Queen Silvia's middle name)
