A century ago, it was quite possible for a guy to have fathered 25 children with just 2 sequential wives and no mistresses. Not sure if that’s at all relevant.

A century passes. Thousands of people are his direct descendants, out of which dozens get DNA tested. Those descendants do genealogy and find each other by various means, FTDNA, AncestryDNA, 23andMe, such as that. They form a rollicking continuous online family reunion.
