My 2 x GGU had 4 children die between 1869 and 1873, 3 of them in the same year in Birmingham, England from cholera, or typhus, and a 5th child died in 1878.
The 2 children who were born before 1868 survived, 3 out of 4 children born after 1874 also survived.
It is oddly more upsetting because the house he lived in is still there about 5 minutes walk from where my cousin his 2 x grt nephew lives.
That is 5 of 10 children, 50% of his children. Even if we ignore the daughter who died in 1878, that's 40% of his children in 3 years.
Can you imagine 40 % of children under the age of 4 dying in any country? Cause of death, diseases that are now preventable because of public health precautions and vaccinations .
