One thing that's entertained me as I've looked at census records covering decades is three great-aunts who only aged about 8 years each decade.
Old census records can be very entertaining. I was looking at some old records of my grandmother’s family in central PA and I noticed a couple of very strange occupations listed. I assume that what happened was that everyone in the area were subsistence farmers, but most also had a trade or some other job that they did, like being a blacksmith or a logger. Well, it seems that couple of them didn’t have anything else to report and when pressed by the census taker, one claimed to be a kite maker and another a card reader, or fortune teller.
But some of the handwriting on the census' is beautiful. They learned to write back when school taught penmanship.
