Randomly looked up two brothers I knew when I was in high school. Their names are more common than I expected ... older brother has hundreds of name-alikes, but none of the ones I found had the right age.
I’m sure he’s split from the wife I knew (she was the chase you down the street with a knife type), but I did find one that had a woman with that same first name as a “friend or relative”.
Younger brother also had a lot of name-alikes, but about half of them are twenty years old (I’m not kidding) ... enough that I wonder whether it is just one person who has moved twice a month since his 18th birthday.
Anyway, I was surprised. Without much effort, I had date of birth, address, cell phone number, and employer. Also current and former wives and a former address in the same building (but not the same apartment) from the high school days.
After all that, I’m not going to contact him. I was just curious ... and found sites that gave me far more info than I sought or expected.
