I don't have a dog in this disagreement, but putting the bar at "dig up the personal details of 10 different individual people and the changing dynamics of their lives over decades _starting from 1880_" is a pretty insane ask I'd imagine. How many resources for reliable and accurate longitudinal case studies from the 19th century are there really? I suppose we could read a couple dozen books written around then but that's just making a satisfactory reply so prohibitively time intensive as to be impossible.
Indeed, and when 10 were pulled up by zozbot234, they say that doesn't count. This sort of discussion is not really useful in my eyes, shifting goalposts around and not saying what one means.
