Lucky marriage?

First my brother gets married with Rhagae and later I get married with Ira without any questions asked. I will explain:

Currently I am almost 20 hours through my very first campaign but a bit earlier than that this happens; me and my party, including my brother that I saved, are in the western Vlandian land fighting sea raiders, taking out hideouts, me loosing more tournaments that winning and so on when I suddenly get the second courier marriage proposal. It is the Southern Empress Rhagae in that proposal?! And at that moment we are just peasants running around trying to make a living in Vlandia. I selected Vlandia culture for my character and thought to join them as vassal but after this all turned around; why not accept this proposal? So I thought I must just then marry Ira, cause why not? Later (like a bit more than half a in-game year afterwards) I just talked to Rhagae to ask for Ira´s hand, no gifts to Rhagae nor any persuasion with Ira what so ever. I have talked to Ira once before for the Neretzes Folly quest but thats it.

Were we very lucky? Or is this happening every now and then? I was thinking it was going to be hard find wifes for me and my brother, much talking and so on. Maybe even paying thousands.

What do you think, a good way to go?
