You come across all kinds of information in the census. Have you ever looked up the occupation of your ancestor?. So far, my ancestors have been a tanner, a carman, a teamster, a pilot, a captain, a stockman, and of course a farmer. Just to be on the safe side, even though I think I know what all the occupations are, I look them up. And as I look them up, I think about the time period. The pilot that I mentioned was on a ship or a boat. I learned that by subsequent researching of the census. And this was in the 1880s, so I did not think he was a pilot on an airplane. What about the stockman? Looking up the occupations of your ancestors helps you write your story.
