Wondering if anyone can verify any information on John Chisum Walling born on June 18, 1819 in Covington County, Mississippi. Died in February 7, 1865 in Bosque County, Texas. He was in the rear guard during the battle of San Jacinto due to illness. Wife was Martha Ann Dorsett. I have recieved info that he was a Texas Ranger in 1836. But this is not confirmed and I would like to know if anyone knows this as factual and where they found it. John is buried next to his father Col. Jesse Walling in Whitney Texas.
