He’s basically saying:
Lycoris‘ mom was a yandere.
Her uncles grandmother was also a yandere.
Lycoris‘ mom and her great grandmother were broken.
Kaffir and Lycoris‘ mom got married to a relative to thicken their bloodline.
(Probably so there was more of a possibility of the getting red hair and eyes.)
Her uncle excepts her to be broken like her great grandmother and mother.
Lycoris doesn’t want to be in her uncles mansion anymore, because everyone is crazy.
Kaffir was a victim of the Lilia family and it’s craziness.
It can be assumed that her family is made up of yanderes.
It is highly likely that both Lycoris’ mom and great grandmother were yanderes as well.
Kaffir’s marriage was most likely political.
Narcisuss probably wants Lycoris to marry shade to thicken the bloodline EVEN MORE.
Do none of the people know the effects of incest ?
