Perhaps you will find this a fun story.
About 80-years ago a man and his wife traveled far from their home to settle where I now live.
I visit them on an occasion. Thinking, "there are a lot of my family out there", "what are the chances?". Only to find I am actually twice related and feel I should have been more mindful. In a large sense I did the same thing they did. I travelled far from home to settle in a place where I had no relations and knew no one.
However, the mister remarried, and by that marriage, I am "Shirttail" related to most of the county! Strange world we live in. Even more odd, she (the second wife) passed away about a half hour's drive from my family home . . . on my birthdate!
Would one call this a "Butterfly Effect"?
