I went down a rabbit hole earlier in the week and read the Wikipedia page of Grigori Rasputin of Boney M fame.

He was born as a Siberian peasant in 1869 where seven of his other siblings didn't survive to adolescence and there may have been a ninth sibling whose existence is unconfirmed.

It's simply not possible for us modern minds to truly appreciate what it was like to exist in a pre-antibiotics world, which makes all of the unmarked graves retconning all the more bullshit.
