That's terrible. I found my great grandfather on the 1911 census and it said 11 years married, 5 children born, 2 children still living, 3 dead. I was shocked that in the 20th century this was still happening. His brother had seven children and all but two died by the age of 21. The two girls who survived lived to 80 and 97. One of my great grandad's surviving two sons (my grandad) died in his 40's of a heart related condition and of his children, one had a lifelong heart condition, one (my dad) had a lifelong progressive disabling autoimmune condition (which has passed on to me), and one had early breast cancer and died of secondary cancer. I had two babies that had to be delivered early due to my renal disease so if i'd had them a couple of centuries ago, probably none of us would have survived. One of them has autism. I do wonder if all of this is down to poor genetics, maybe a result of people marrying their cousins way back in the 1700's.
