Other important theorists of the 19th century were John Stuart Mill and Wilhelm Dilthey. In simple math, a generation is between 18-20 years, so every century has at least 5, but more likely 6 generations born during any given century. Go back a bit further, and you reach a date when our family trees share not just one ancestor in common but every ancestor in common.
