Ancestry has taught me some strange lessons – in math, history, genetics and personal stories. It has defined the word “serendipity” for me. I’ve learned so many things that have nothing to do with who my great-grandparents might have been.
An example: 80% of all marriages in history have been between 2nd cousins or closer. This is because of the lack of suitable mates outside the 5-mile zone of a typical person’s reach for most of history. Without war or some similar disaster, people stayed put in their little worlds.
I’ve found a lot of fascinating things along the way, including people’s missing birth fathers, birth certificates, and even ties to royalty. (For what it is worth, you are connected to royalty. It’s a certainty. Wealth contributed greatly to lineage and it also afforded people’s connections to be recorded, unlike most commoners.)
