Enumerated in the Census Twice?

It happens more than you think--someone listed in a census more than once. My grandmother is enumerated in 1930 once with her parents and once in the household where she was a "working out" (the kids always thought that meant she was exercising...)

There are also several well-known people who have been enumerated more than once:
1850 Mark Twain
1860 Robert E. Lee
1880 Frank Lloyd Wright
1880 Rutherford B.Hayes
1900 Humphrey Bogart
1900 Katherine Anne Porter
1910 George M. Cohan
1910 Jack London
1930 Charles Lindbergh
1930 Thomas Edison

Keep looking, you may find your own person more than once.
