Absolutely loving this game! Although have some questions I can't seem to be finding answers for.

I'm nearing mid-late game in my first playthrough as Sturgian Vassal. Here are some questions I need help with. P.s not using mods.

Is there anyway to marry my daughters with my favourite minor clan nobels. Such as Jawal and Lake Rats? And if I do that would i be able to use them more, or recruit their units more often?
In the middle of a seige battle how to ask some units to use my siege weapons, or abandon them?
What happens to nobels of say the western empire, when the western empire is no more?
If my Hero death is switched off, can the wife die in childbirth?
How to equipped banners actually work in battle? Do comapnions drop them, can I command them to use it in one area? OR is it just passive.
