One great grandfather, and all his antecedents for about 300 years, was the town undertaker. He was very disappointed when my grandfather grew up with a phobia of dead bodies and refused to work in the family business as expected (he ran a timber yard instead and was a brilliant woodworker, assume he started off helping with coffin making).
Another was a farmer. His male children carried on with that until the 70s when they retired and sold most of the land after building properties on it. That side are pretty wealthy now!
Another was a docker. Not sure about the 4th, I should ask my mother. He may have been a docker as well.
