This is getting a bit off topic, but advy's aren't "black sheep". A black sheep of the family is still part of the family. And if you're part of the family, then you're a noble. Advy's aren't nobles. If they were, they wouldn't be advys. Advy's aren't nobles. so they're not part of the family. If they were, they wouldn't be advys.
They can't be associated to the family. If they were, then they would be nobles, and not advys.
Anyway, it's not really a big deal. it's an easier way for new players to get the fame they need, and in that context, I don't think this is something worth changing.
