@fuadhika The Randolph house can be inherited by Silk's child. There's even case the King's crown was given to the grandchild of the king and the king son remained a prince.
@PDugna as things stand, he would need to take over her family territory and responsibilities, if he married Silk. He still needs to set more stuff up, to not get saddled with more responsibility than he can handle.
@Kllick Even if that's possible the Randolph House would be heirless until that child is mature enough, a noble house as big as Randoplh (Marquis or Duke I can't seem to remember) can't be heirless for that long, he'd be better off adopting an heir rather than waiting for that child. A regent would be fine too I guess, though I don't know if that's allowed for other than the King.
@PDugna@dethduck there is no benifit in marying both daughter in the same house nobles tend to mary for politics or to tie family into ang alliance so marying two daughter to one house instead marying them to different house has no benifit politicaly.
