TURNBO / COSPER
   In 1857 a son of Hugh and Mary "Polly" (Powell) Turnbo moved from Wayne County, Tennessee 
to Bell County, Texas. This son, Andrew Jackson Turnbo and his wife, Louisa Pigg, settled on 
the southwest side of Bell County, not far from the Williamson County line. He was a horse 
breeder and farmer who raised five children, a daughter and four sons.
 By the time these children were adult, a second wagon train had arrived in the same 
Bell/Williamson counties border area. This wagon train arrived from Alabama in 1870 led by 
Rev. Joel Henry Cosper. He and his wife, Millie Eliza (Bagby) Cosper, had fourteen children, 
and a number of them settled in the area. Four of these children married into the Andrew Turnbo 
family or thier descendants married.
   In 1851, having left Wayne County, Tennessee where they had married in 1830, James Hill and 
Jane "Jennie" (Turnbo) Casey helped to found Williamson County. They settled on the north side 
of the county and were, therefore, not too far from where Andrew and Louisa settled in Bell 
County. Though some contest Jane's identity, many Turnbow researchers list her as the eldest 
child of Hugh and Polly Turnbo. If this is true, Andrew was settled not far from his sister. 
Even if not true, he had settled near a relative. Two descendants of James and Jennie Casey 
also married descendants of Joel Henry Cosper.
