Found something for his wife's maiden name.
On there child George Washington Turner on the Social Security Claims Index it lists
||Mary C Henderson|
||George Washington Turner|
Original data: Social Security Applications and Claims, 1936-2007.
As per his correct parents. I haven't found a specific source to verify but some tree's would allege his parents to be
John M Turner
Birth 1803 • South Carolina, USA
Death 31 OCT 1837 • Benton, Lowndes, Alabama, United States
Sarah Elizabeth Hanks
Birth 17 JUL 1797 • Greenville, South Carolina, United States
Death: Unknown Cleburne, Alabama, United States
However on further research this appears to be unlikely
