I have several healthy, young and fertile kinswomen at my court. Unfortunately, no one wants to marry them matrilineally. I tried looking for duchy and county title claimants, the default search list, lowborns all over the world and no one wants to marry them (Your kinswoman is unimportant: -----). The reason why i want to marry them matrilineally is because i want them to breed more kinsmen so i can further strenghten my dynasty and occasionally get a weak claim or two, but it seems i am only able to send them off into regular marriages, which to me, seems like a waste of good women, since they dont even give me alliances.
Is there a way to lure some sucker from another court into marrying them matrielineally? Also, incest is not an option, i dont want to risk having inbreds in my glorious dynasty.
