I have a little COGBURN info. May help. My grgrfather was Jackson Cogburn. He had bro named Tomlison Ford. The were b. Washinton Co GA. I believe their father was Cyrus. Jackson settled in Newton & Sabine Co TX while his bro stayed in Rusk Co around the Mt Enterprise area. There were some Cogburns around the Timpson and Buena Vista area, but I have'nt had chance to look into these yet.Hope this helps.
