As Kim C suggests, there is a lot on the genealogical search sites. I have been checking back on a monthly basis and always find some new list to peruse. Some of the local lists give email addresses of volunteers who will check for you. I had Hales Index (CT) and the 1790 census checked this way. Sampubco in Salt Lake will furnish copies of wills, which can include useful data. 1810 census data is available for a price.
