Re: Information on John Sullivan Washington Baptist Church, Pelzer, SC 1822 -1839

The death certificate for D. P. Sullivan (Daniel Perry) lists his mother as Mary McDooley.I'm looking for a William Sullivan who m. Martha Townsend (1839-1920).They apparently lived in Anderson Co., SC and had at least one son, William Riley Sullivan (1862-1932).I can't seem to find these people on censuses and am wondering if you have any info on Sullivans who lived in the Pelzer area.Would appreciate any help.
