This reminds me of a humorous thing I uncovered about my 5G-grandmother’s second husband. When he first appeared on the census, he was 15 years younger than her and working a day laborer. (It was after the Civil War, I guess eligible bachelors were hard to come by).
By the next census he had closed the age gap by 5 years. In his final census appearance he was not only a full 8 years her elder , he was recorded with the honorific of “Doctor” at the age of 70. The man was certainly an achiever if nothing else.
