here are some details about Delphine siblings. As I said before, this information was given to me by a friend, and even if I believe it is correct, I did not check myself, since this is not my family.

According to my files, Alfred and Cordelia had 8 children, all of them being girls. Quite surprising. I must be missing some other children. If you find something about them, I would be happy to know, as well as details on Roland's children.
