Jesse Cobb served in the War of 1812; documents exist to prove this. His unit did serve part of the time in GA. After this war he returned to VA to live and then to TN to marry and raise a family. His parents were Thomas Cobb and Betty Willis who married in Campbell Co VA on 3 Dec 1788. Supposedly Jesse's parents may have followed him to GA during this time period before returning to VA. There is some documentation to show this but not to prove it 100% in my mind.
