Thought you might like to see a James Gillespie rifle (Note James used JA G to differentiate from his brother John who signed his rifles J G) I believe it may have originally been a flint rifle converted to percussion, based on cutout for flint cock. (if so the lock was replaced). James was the fourth son (of five) of Mathew and Elizabeth Sitton Gillespie (all five were trained gun makers).
James Gillespie followed his older brother John R. Gillespie to Union County, Georgia shortly after John moved there in the late 1840’s. The 1850 industrial census shows the two of them working together in the Blairsville area. Later, after the two married, John moved to Young Harris in nearby Towns County. James remained in the Blairsville area until his death in 1897.
I tend to believe this rifle was probably built in Mills River NC prior to his move to Union County GA in 1849.
