Playing as Brabant. Noticed a dynasty with the name 'van Brabant' living in Moers.

Currently playing as Brabant. Just saw a dynasty with the name 'van Brabant' living in Moers. Guess I'll have to conquer it so I can start the process of changing my ruling dynasty to 'van Brabant'. Not doing it would be such a shame. 'Real Endgame Material'.
