Keeping up with the Dursts

As a noble, Elizabeth married for fame and power. Gustav, being a good adventurer, would have brought glory (CLOUT) to the family.
Gustav and his friend Rell both wanted Elizabeth, but Gustav ended up marrying her.
We find out Gustav is kinda shitty as well. Elizabeth aged, and he proved himself to have no taste whatsoever and started going after the young nursemaid, Margaret.
Apparently, so did Rell. :)
Walter is Gustav’s child with Margaret.
Rell one day got pissed for some reason or other and just killed Margaret.
We find out that Elizabeth also murdered Gustav.
At some point, Rose and Thorn heard Elizabeth, Gustav, and Rell hit someone over the head with something really heavy.
Margaret found this out, and locked Rose and Thorn in their room. Margaret was found and killed by Rell; Rose and Thorn were trapped in their room and starved there.
This may be related to Gustav’s murder hobby, if Margaret finding that out was what prompted Rell to kill her.
