Interesting topic..
My paternal grandfather worked for Lorillard Tobacco Company in Kentucky for 40+ years. His father was a farmer is Eastern Ky. Dont know anything about my grandmother's father. She died when I was 3.
My maternal grandfather worked for American Standard for 35+ years, and became a preacher the last 15 years of his life. He raised me so I was very close to him. One lasting memory that sticks out with him comes from a reunion of sorts he had at American Standard during the last couple of years of his life. I went with him and he showed me the very hot foundry where he spent over 30 years of his life. I never remember he missing a day, sick or not. Lots of respect from me. I guess that's where I get my work ethic from. His father was a coal miner in south central Ky.
My maternal grandmother's father's life was pretty much kept a secret from me until I was around 20 or so, primarily out of shame. He was a bootlegger and gambler from the sticks of Kentucky. The story I was eventually told was that he got all liquored up during a poker game, thought someone was cheatin and lyin', shot and killed a man. Died in prison of TB. Don't know anything about his father.
