I am trying to build up a nice family tree, with good genetics and the rest.

One general, Francis, is the most perfect General you could wish for.

He is a Born Conqueror, Physically Striking, top level Fertile, etc. and by the age of 26 or so was 10*, with Enjoys The Dark, Promising Attacker and Defender Traits. He has Chivalrous Knights and all sorts of other retinue people, and the only bad thing on his card is a Pagan Magician.

Yet age 36 he has had no marriage proposals. Neither have several of my other Generals - the only proposals come for the women family members.

Same with the only other 10* general I had on a previous game. Why can't the good genes get passed through??
