I don't know if this is your Robert Brightwell or not but just in case it is-- There is a Robert L "Bobby" Brightwell, son of William Thomas and Minervy Brightwell. William Thomas Brightwell was born abt 1815 in South Carolina, died after 1870 in Preston, Webster County, Georgia. I do not have a confirmation of spouse, could be Josie. The 1920 census for Robert L and Josie lists Ga as parents' birthplace instead of SC so it could be either a different Robert or the census had the wrong birth state, either is possible. My William Thomas Brightwell is the son of William Brightwell from Barnwell, SC, b 1784 in Barnwell, SC. William Thomas was the brother of my ancestor John Jackson Brightwell. William b 1784's father is Runnell (Reynolds) Brightwell, mother is Mary. Runnell had three wives (I think, notes are at home) so it gets confusing as to which child belongs to which mother. I hope this helps you, feel free to contact me further.
