I  recently acquired the 1790 SC census and will do lookups. One surname per 
letter. If all you have is a surname then send the county name. If it is 
likely a very uncommon name then maybe I can check for the surname for the 
state.  I just don't want to get "all the Smiths in SC in 1790".  :) Send the 
request for a look up to :
Lookuplady@aolcom. Do not send the requests to [email protected]

The index in back is by name.  I go to the name and it gives me the page in 
the book.  for the county, I go to the page and there on that page will be 
the county census. Usually more than one page per county.  This is a good 
chance to locate the county your ancestor lived in for the year 1790.  The 
census age categories are:1]  Free white males 16 and above; 2] Free white 
males under 16; 3] Free white females; 4]all other free persons; and 5] 
slaves.  0-0-0-0-0 format.

Happy hunting all!
