I think it really would have to be a given that the DuPres family were Catholics--there weren't a whole lot of titled French Protestants at that time period.
Warning to LP fans--sorry, but this is my opinion. You might want to hit page down.
I don't think much of Parker's novel. Overblown prose, Amos 'n' Andy dialect that would have been much better left unattempted, no real attempt to jive with the already existing canon, on the trite side. Thank God, I didn't spend money on the thing.
Dreams of the Dark though is definitely worth getting--Mark and Elizabeth Massie (sp?) did a great job with the book. I have to disagree with you, VAM, I thought he used Victoria much in the original spirit of the early episodes. And I absolutely loved the new character.
As for Josette's mother, we have a number of options: death in childbirth (either from Josette or from another child that didn't live), diseases of all kinds (cholera, TB, cancer, influenza), accident, and the list goes on.
I really don't see Natalie as being Josette's real Mama. No set up for that at all. Her devotion to Josette seems natural enough, particularly if Mama died and left pauvre petite there motherless, it's logical that an aunt would feel the need to step in and be there.
