Yes to Nin probably being the head of her own household. That's just how you flavor their living arrangements.

Thanqol, that looks very solid. I quite like the image of the powerful bear knight you've created, and I agree with Numbers that the horse is inspired. 

Also, a reminder to both Thanqol and Numbers that enchanted items in Dark Age always come with a "maybe" attached to the enchanted bonus. That is, you always get the numerical stats, and they "might" protect you from some special harm or have some special affect on a foe. It is possible this will be denied by some other magical effect (and you'd be in a position in which your Right related to the item was denied) or that it will fail if you roll very poorly, although I will use this sparingly.

Last thing, take a look at my suggested Stronghold options a few posts back. I didn't completely fill them out, that's supposed to be a group choice, so if you have thoughts on it, please suggest them. If you don't care, I'll make some suggestions later today. 

Expect an IC post this evening (US West Coast) or maybe tomorrow morning. Going out hiking now, so I won't be around for much of the day.
