Pip, love the photo! Just how I have felt on many occasions!
Just this past week, while working on a new line for our niece, I did a brief biography based on a census record where the female head of household was 29 years old (already a widow) and had the proper seven year old son. But, also there were children ranging in age from 19, 17 , 15 and down to the seven year old. I thought those older ones must have been the children from the first marriage of the husband. WRONG!! When I found two more census records for the wife - her age was totally wrong on that 1850 census. She was definitely the mother of those children. So, back to all the bios to fix that information!!
