I have tried to find the parents but no luck. I did find that Sampson was a private in the Mexican war and enlisted in 1847. In the enlistment list it is indicated Warren County, but it is marked as being in Georgia. There is a Warren Co. in Georgia. He was 6 ft. 3 1.4 inches tall, was 27 yrs. when enlisted and had hazel eyes. I will try further but the records were not very good back then. I wish you luck in finding out more.
