All 3 of these records show my Great Grandparents Dan and Bridget as well as my father's uncles. The difference in birth dates (1831, 1832, 1833, 1836 and 1836) could be beacause Daniel was Illiterate or the census taker was. But, It could also be the date when the census was taken possibly at different times of the year which might skew the age by a year.
