Monarch Child Mortality
There is a strongly positive relation between childhood mortality and family wealth This holds true except for certain niches, the most famous being low-income Asians that are rich enough to buy white rice instead of brown rice, but not rich enough to afford lots of meat, vegetables, and fancy medical care.
I wonder if another group of the wealthy with surprisingly poor outcomes was the top level of the pre-modern nobility due to inbreeding and infection (a combination of an urban environment and the number of people with whom a monarch would come into contact). Would your average Queen or Duchess have had fewer surviving children than the wife of a Baronet?
