I think there is just no public information about the second branch of the family...
I remember sometimes visiting that page,
and it seems like many celebrities have no information at all, especially about another branch of the family and so on.
Genealogy is quite exciting, and many of us hardly do it more closely.
I don’t think Alizee herself knows her family tree very far back, or at least many of us don’t know a few generations beyond... but I wouldn’t be surprised if Napoleon, for example,
were somehow related to her — at least both are absolutely amazing conquerors.
[albeit in very different ways! - Alizeé’s conquests are always beautiful and good!!
