Onesimus Futch, Sr. was born about 1735 in Beaufort, Carteret County, North Carolina or Craven, Bath County, North Carolina, perhaps the son of Martin Futch and Isabella Lawson Futch, as per research by the late John Wise. Find-a-Graver Shirley Ann Denmark makes several important points concerning Onesimus Futch, Sr. First, John Peter Futch and Katherine McAlister Futch may have been the parents of Onesimus Futch, Sr. Second, Onesimus Futch, Sr. may have died in 1809, as per DAR and SAR records, rather than in 1832. Onesimus married Anne Duke Futch, and they had nine children: Onesimus Futch, Jr., John Futch, Solomon Futch, Sr., Aletha Elizabeth "Celety" Futch Lewis, Thomas Futch, Jacob Futch, Isaac Futch, Martin Futch, and James Futch. Onesimus Futch, Sr. was a Revolutionary War veteran from South Carolina. The Futch family had lands that straddled the Bryan and Bulloch County line in Georgia. He died either about 1809 or in 1832 in Bulloch County, Georgia and is probably buried in the old Futch Family Cemetery, now underwater in Bulloch Bay, in Bulloch County. Onesimus' ancestry was German, and the original spelling of his surname was Fuchs. In German "Fuchs" means "Fox."

The late Futch family genealogist John Wise writes that the old Futch Family Cemetery is located "east of Statesborough (not Statesboro), in the lower southeast 'Bay Area' of Bulloch County, Georgia. DAR Revolutionary Soldier markers were placed on the graves of Onesimus and his sons in July of 1918. Unfortunately, this family plantation cemetery was later destroyed by the U.S. Army Corps of Engineers during a 1941-1943 area drainage project. The site of that old Futch Family Cemetery is said to now be underwater, near the eastern bank of Bulloch Bay in lower southeast Bulloch County, Georgia. It is unknown if any remains and/or gravestones were relocated from this old family cemetery before it was destroyed."
