The Bad Old Days--My Dead Cousins

I was the youngest of 8 first cousins, 2 children in my family, my paternal uncle had 2 children, one maternal aunt had one child, the other had 3 

Those figures are what I was aware of.  But in fact there were 3 first cousins who died young, 2 as babies and 1 at age 7.

My point: if I rely only on my personal experience life in the US looked good and safe, but that's misleading because I don't see my whole cohort, just the survivors.
