Sam Trollinger is on the 1860 Black River, Reynolds County, Missouri census. Page 12, line 16. I'm not directly related to the Trollingers. My Harbison line is connected in various ways to the Trollingers and Westermans and Bells. John and Elizabeth Harbison Bell (my 3rd great grand aunt) were the parents of James Stacy Bell, of whom I was inquiring regarding his death. James Stacy Bell married Lucinda Trollinger, daughter of Absolom Trollinger and niece of Sam Trollinger. James Stacy Bell's daughter Stacy Lucinda Bell married, as his second wife, John Jefferson Harbison, my 2nd great grandfather.
I can't find much on Coffee's Regiment, and I haven't been able to find anything about James Stacy Bell being a prisoner and nothing about his death.
