Early patents index

From the days when the Midwest and Northeast were the invention headquarters of the world . . . new on Cyndi's List is 19th Century Patents, an alphabetical index to inventors by name, including all those who obtained "X patents" from 1790 to 1836 and "the first 10,000 utility patents (1836-1853)." Residences and patent numbers are included.

If you have an inventive research target from that era, let me know how you do in finding any of these folks via Google Patents or the US Patent and Trademark Offoce website. I've had very mixed results.
