It seems fair to take turns, so we can all share the blame.
A quickie question though - how many historical events are we rolling? You write that we're an ancient house, but you rolled a 6 for First Founding, which in my book should make us a new house (and in fact a house founded well after the campaign date).
If our resources end up really terrible we can always take up Ser heretic's offer of a fix - perhaps convert all the initial resource rolls to the average results and apply our individual and historical rolls from there.
How's your character coming along, BTW? Have you decided what age category he'll be? It's looking like my character will most likely be middle aged, and a direct member of the family. If you're still set on playing an adult or young adult, I could see myself playing an uncle of yours. Also, as head of the house, are you set on taking direct control of managing the house and thus making our House Fortunes rolls? If not, a couple of my concepts have the room to be a passable steward.
Oh, and here's my first contribution to our historical events:
Historical Event: 3d6 15 = Villain (Influence +1d6, Law -1d6, Population -1d6, Power +1d6)
Influence +1d6: 1d6 3
Law: 1d6 6
Population: 1d6 4
Power: 1d6 2
Hmm, I gotta say that orokos really seems to be stiffing us. All positives are low, all negatives high.
