The Legend Of John Wilkes Booth

[Susan Higginbotham]

There's a good article about the census here. As it points out, taking the census was far from an exact science. People got missed.

As someone on the blog linked to below pointed out in response to "glomfeld" (would that be you, by any chance?), Lincoln may have been in Taylorsville on the date the census was taken, so perhaps that's why he was missed.

Or perhaps there was a Great Conspiracy to obliterate Lincoln from history by omitting him from the 1840 census. If so, it failed pretty miserably.
