Tips?

I just downloaded this game called Sword of the Samurai, which is taking up way too much of my time.  It's an old game but very compelling.  You start as a samurai with a fief in the Age of Warring States, and work your way up from there to Hatamoto, Daimyo and Shogun.  That is, if you do it right.

Problem is, I don't have the instructions for it, so I don't know how to do everything.  I'm wondering, if your character has a daughter, is it possible to arrange a marriage for her, and how is that done?  Anyone here know?
