I searched some newspapers for the possibility of finding the death and burial location of Elder William Moses Pruitt. I haven't found it yet, but I did find an obituary of his wife, Mary Etta Sasnett Pruitt. I am transcribing it here.
Died, at the home in Smith county, Texas, on Jan. 26, 1899, Sister Mary E. Pruitt, wife of Elder Wm. M. Pruit. Sister Pruitt was born in Talbot county, Ga. Professed faith in Christ and united with the church in early life; was married to W. M. Pruitt July 31, 1850. Eleven children were born unto them, nine of whom are living, M. B. Pruitt being clerk of Rusk county, which office he has filled with satisfaction to the people for nine years. She came to Rusk county, Texas, in 1871 and moved to Smith county in 1896; she leaves a husband, five sons and four daughters. Sister Pruitt was a noble woman, of strong christian character; devoted to the church, zealous in good works and beloved by all who knew her; a devoted wife and loving mother. She died as she had lived, strong in the faith, and fell asleep in Jesus, and was enabled to mark the wonderful change with her last words, "What a change." We would say to the sorrowing ones, weep not; thy wife, thy mother, is not dead but sleepeth. For beyond the misty river of death, in the sweet paradise of God, "where the wicked cease troubling and the weary are at rest," she awaits thy coming and the glorious resurrection of the body. Yes the evening shadows gathered and the long days work was done; and she has reached the sweet rest beyond the setting sun. Let us look by faith and press on to that sweet rest where there is no anguish or parting. W. H. H. H.
This was found in The Henderson Times (Henderson, Tex.), Vol. 40, No. 10, Ed. 1 Thursday, March 9, 1899, page 2. Mary E. Pruitt is buried in the Old City Cemetery in Henderson. W.H.H.H. is William Henry Harrison Hays, a Baptist preacher in Rusk County. If anyone knows where W. M. Pruitt is buried, I would like to know.
