I am also working on the Jacksons of Macon County. I hope this gets to you since your post was 2005. Cap is the son of St. Clair Jackson. Cap's brother George is my GGrfather. St. Clair died in 1909 in Bellingham Washington. George is buried in Nocon, Texas. I am looking for the parents of St. Clair Jackson, born in Ohio in 1834?? I think.
