I found this on another genealogy site so I don't know how accurate it is. It may give you some clues for further research.
Re: Shadrack Jacobs 1765-1829 South Carolina
Shadrach Jacobs came from Fairfield County, South Carolina to Wayne County, Georgia in 1809/10. He lived there until 1829 when he was returned to South Carolina, tried, convicted and hung for a murder that he committed before he moved to Georgia. The jury that convicted him recommended that the judge have mercy on him, but the judge stated that it was up to his Maker to determine any mercy. This crime occurred when an attempt was made to arrest him on a misdemeanor warrant. Information in the Winnsboro, SC Genealogy Library indicates that the State of Georgia requisitioned his body. It is not known where he and his wife are buried.
He married Keziah ?. They are believed to have had several children but only one, John, is known to have come to Wayne County, GA.
1810 & 1820 Census shows a Shadrach Jr in Washington County, GA. This coincides with Sr. leaving SC. The census shows Jr to be a lottery land holder near Sandersville.
In Georgia Shadrach served as Justice of Peace, 335th District, Wayne County, 1817-1825, also militia captain in the same district, 1816-1821. He was a private in the War of 1812, serving in the company of Wayne County Militia under Capt. Isham Walker, 1813-1814. His son, John, married Capt. Walker's daughter, Keziah. Shadrach and his wife were members of the Big Creek "arm" of High Bluff Primitive Baptist Church.
Shadrack served as a private in the South Carolina Militia during the Revolutionay War.
Records also shows that he owned land in Fairfield County, South Carolina before coming to Georgia. One of the documents in South Carolina is signed by his wife with an X.
From a Feaster Family History (babech@mem.net):"Andrew Feaster, Jr. ... died January 25, 1808, being shot by mistake for Ezekiel Woolley, his brother-in-law, who was the Sheriff. The latter had summoned a posse to assist in capturing a criminal, Shadrack Jacobs, by name, and Andrew Feaster, Jr., was one of the number. It was after dark, and Jacobs shot Andrew, who was riding the Sheriff's white horse, and had on the sheriff's hat. Twenty years later, he was brought back from Texas {sic} and was hung in Winnsboro for the crime. He, Jacobs, stated that he had supposed the rider of the white horse to be Wooley, whom he had sworn to kill, and regretted deeply having shot Andrew Feaster."
