By 1835 there was a group of Choctaws living on Attoyac Bayou in what is now Panola County. Most of these to my knowledge left Texas after the Cherokee War in 1839 with the exception of a few mix bloods that settled near a group of Cherokees in Rusk County. By 1851 more Choctaws related to the early group settled south of the Cherokee community near Overton, Texas led by Archibald Thompson a quarter blood Choctaw-Chickasaw. His first wife was a Jackson and believed to be the daughter of Bill Jackson who is on an early Choctaw muster roll. This Jackso was believed to have been part of the early group in Texas, but there are no names of them to provide any real proof. Another of Jackson's daughters and a niece married Henry Thompson the full brother of Archibald. Their brother William was in Texas in the spring of 1840 trying to get land from the Republic of Texas along with two Cherokee half bloods. He later died in the early fall of 1840 at Fort Towson, Coctaw Nation. Also you might want to contact the Jena Band of Choctaws in Louisiana as the Jackson family is well represented there as well. Hope this helps J.C.
