Pretty wild Ann but I realize all too typical of the common family experience back then.
I have the conversation with people from time to time about life expectancy. There's a common perception that because it was so much lower in centuries past than today that no one, unless very lucky, could expect to live long. In reality it was more the prevalence of young deaths that were so much more common weighing down the average. But if you were able to clear a few hurdles and live healthy into your 30s or 40s you had an excellent chance of reaching into your 70s and beyond. Nowadays if someone does in the early-70s it seems almost premature, and for good reason. My father just turned 70 in July and I would be shocked if he didn't make it at least another 15-20 years.
If you take the averages of a random poll of ten people from a century ago and compare it to today it would often look something like this...
Age at death - 1914
5, 10, 25, 75, 75, 80, 80, 80, 90, 90
Age at death - 2014
25, 75, 75, 80, 80, 80, 80, 90, 90, 90
The average of the 1914 crowd is significantly younger, 61 years, than their 2014 counterparts, 76.5. But that's largely because you have a 5 year old who died from TB, a 10 year old from meningitis, and a 25 year old mother during child birth. 70% of the group still managed to live to at least 75 years of age, and the average of that 75+ crowd is nearly identical a hundred years ago to today.
All that said families needed to be well aware that their "heirs" had a frighteningly good chance of not living (or not living long) into adulthood. I wonder sometimes, as we see in many cases, if the power and money possessed by these royals clouded their perspective. A sort of, "it couldn't possible happen to our child" mindset.
