Who exactly uses the Family Survival Rolls in BoE?

I'm assuming Wives still use the rolls from the core rulebook since there are no provisions for Player-Knight Wives in the BoE tables. Is this assumption correct?

What about PK children?

Yes, when it comes to childbirth, but the KAP 5.1 table has way too high childbirth mortality (10% chance per year means that very few wives live much more than a decade, making them disposable baby machines, which is something that bugs the hell out of me when I am trying to do a multi-year love story). I'd rather use the BotE table for PK wives, too, and just add twins on 13.

Alternatively, you can do a quick fix of KAP 5.1 by making 11 "No Children".

My preferred solution for childbirth is here:

When it comes to NPC survival (so just the death chance, not the childbirth death or child born results), then you should use BotE for PK wives, too. This, by the way, is partially why it would be much easier to just add the twins in and do it all in one roll.



What about PK children?

They use BotE table. 10% child mortality for 15 years means that you have 1 survivor out of 5. That is insane.

You'll only have to take a look at the childbirth mortality (20% chance per live birth) and the child mortality (20% survive to adulthood) to realize that the human race is doomed to extinction in RAW KAP 5.1 rules: each woman is lucky to have 1 surviving child, meaning that the population halves each generation.

In KAP, they immediately die on 11-12 (10% chance) and in BoE they roll a 2nd time on a 1-2. Then, they die on 1-10 if I read that correctly. What are the probabilities of dying in BoE?

See the Pretzel Book of the Estate in this post:

However, that doesn't take into account the female childbirth mortality.

In this thread I was calculating the quick fix KAP 5.1 option (drop mother and child die in childbirth):

You can of course calculate the BotE female mortality quite easily, since it is 5% per year (10% chance of a second roll, which is 50/50). Assuming that the women would have like 25 years of possibility of childbearing, this would give:
Just married 100% survival
5 years after 77% survival
10 years after 60% survival
15 years after 46% survival
20 years after 36% survival
25 years after 28% survival

So the chances are still not excellent, but at least it is a bit closer. Probably, with this in mind, what we should have done would have been to abolish the additional childbirth roll altogether and simply have the men die more often violently on 6-10 on a second roll and the women at childbirth on 6-10 on the second roll, and that would have done it. Still, it is a marked improvement of the 10% yearly mortality rate in KAP 5.1, where you needed a new wife every 5 years or so...
