Currently working California with 1272 hits, many duplicates that need
to be filtered out so
it is slow going. It is about the last needed to be done. You can
peruse those currently on line
You will also find many state censuses that were done between the
federal ones. i.e. 1885, 1895, etc.
Also Canadian censuses back to 1851.
The available 1790, 1800 and 1810 censuses have been redone and are a
lot better to read.
