Got some info on Five Dukes. Here are five of the famlies that have been included among them: Venomania, Conchita, Oruhari, D'Autriche, and Donald (ドナルド).

The D'Autriche members are the forefathers to the Lucifen dynasty. The Donald family came in after the downfall of the (I think) Venomania's.

There's a bit about the Donald's and the "alientation" (離反) of the D'Autriche's, which seems to be a result of the weakening Empire and loss of prominence as a family, leading to their title being neglected.

Based on that, it's possible the Oruhari family are the last remnants of the Five Dukes.

No mention of the fifth family that existed before Donald and Conchita came along.
