Well done documentary. As soon as you mentioned the many Graves in 1917-18 I knew it was the Spanish flu. Years ago I wandered through a cemetary in Elgin IL that had a child’s section. Most of the dates on the markers were 1917. I mentioned this to my grandmother, and it was she who told me about the pandemic. So sad. My grandmother was born in 1912. She was one of the lucky ones.
