Fun with census records

I love the English census records, except when I don't. :-)

Here are a couple of ways the census data can muck you about:

John Suffolk, the case of the man who didn't age

John Suffolk died on the 18th of November 1852 'aged 65' from natural causes related to intemperance, which would make his year of birth somewhere around 1787. (1) But was he actually 69? John Suffolk was illiterate and seems to have lost track of time for the period between his conviction and his marriage in Australia to fellow convict Elizabeth Cockshall.
