Family tree

I am getting lost at times in relation to the family tree. I do not know if someone else has this issue.

The chapter about Marie Lazare was an emotionally difficult one to read for me: it describes abuse of a young child and also I find that it has a "darkness" apparent in the chapter, maybe it would be better to use the word "weakedness"?

Marie Lazare is abused and Marie Lazare takes her revenge in a way against Leopolda.
