Bela is passed off as Rowland's son, so it wouldn't exactly be two separate families.  And I don't think it was particularly unusual for married children to remain with the parents for a while.  Unless I'm mistaking medieval/Renaissance English culture with another culture, which is completely possible.  But I'm still fairly sure that there wasn't much urgency for adult children to move out of their parents homes back then regardless.

I was pretty busy yesterday, so it's fine.  Didn't get around to responding to anything anyway.
