Not so far. It doesn't appear that you need marriages to affect diplomacy since there are so many other factors: demand/offer money, demand/offer province, trade rights, map exchange, safe passage and various other things. It also seems the AI factions are well programmed to use these functions in both initiating and accepting offers as well as countering or refusing inadvantageous offers.
