So an average of around 3 a year? And starting in the1890s? Child death from disease wasn’t exactly unknown back then. They want to act like this is the Third Reich.
Idiots.
A mass grave indicates they were buried all at once. There are likely other graves. So 215 is not the total death count. The burial of 215 children was not remarkable enough to merit a marker.
Another poster cites one of these government schools with a 40% death rate.
