But, Mom's rich cousin was a ..
.
captain of industry.

I'd say "baron" but he didn't achieve that standing. His family was interesting, although his son my age had no interest in even talking to me. His sister, Mom's age, was the nicest of people and kept her small home and yard as neat as a pin.
His father was one weird dude. On fall visits to his only daughter, he would stop by my uncle's house nearby with a load of squash in the back of his old pickup. For 5 or 10 dollars, my uncle would buy these from him. Mostly, they went to his cattle ... I guess the cash paid for the 30 or 40 mile drive to visit his daughter.
The rich cousin seemed to be a polite guy who would "drop by" to visit Mom and Dad after retirement. His son sold half his company ... turns out ... 1 year after his father's death. Purchaser was a European engineering conglomerate. The other half ... was sold 2 years later to "a private equity firm." - Journal of Business
Owned airplanes but he had 3 kids and step kids. His oldest son is my age and lives in a neighborhood about 30 minutes and several socio-economic classes away. Zillow has info on a few homes there ... 4,600 to 10,000 square feet ..!
NyBoy, you are responsible for me knowing that!
