Hi:  You can find a few census records for 1830 and 1840 for some SC 
counties(they were districts then) including York, Spartanburg, Union, etc. 
on the USGENWEB site as follows:  http://www.usgenweb.org/  - from there 
click on states search engine.  Choose SC and fill in blank with census.  It 
will take you to 133 entries, which include some for 1830 and 1840.  Some are 
From the census index book pages only (which is nice because they are 
alphabetized) and others give you the actual info. on no. of males/females, 
etc. in each household.  There may be another site where you can find census 
info. transcribed, but this one is the only one I know of.  Good luck.  
Bonnie.
