Now suppose you're a mongol christian with Agnatic Primogeniture succession. We know that mongols are hardcoded Agnatic, and assume my entire realm down to the lowest barony is Primogeniture.
Suppose I decided to matrilinearly marry any female of my dynasty and give the husband a land. This husband will create some sort of branch family of my dynasty thanks to the matrilinear marriage. Now suppose some time has passed and the branch family is dying for several reasons (maybe lack of male successor, celibate, castrated, etc.). My question is simple: Who should succeed the title?
