Hey Frank,
My great great maternal grandfather was named David J. Hendrick. He is listed in the S.C. archives as serving in the 9th Infantry formally known as the Pee Dee Legion until a restructuring in 1862 when the S.C. 26th Vol. Infantry was formed. He surrendered at Appomatox. David had a younger brother named William who was killed at Petersburg in April 1864. David was in co. B and William was in co. K. I have interesting letters about Williams death. One was written by David back home to Chesterfield County to tell his parents about his brother being killed. Another is from a nurse who treated William in the field hospital to his mother. Another one is from a hometown friend of the family who was also in the army in Petersburg telling the Hendrick family that William had been wounded. One interesting comment in this letter was that he said that " the people of Petersburg said freely that if it had't been for the brave South Carolians our beautiful city would have been in ruins". David went on to surrender at Appomatox. I have other ancestors on the Sellers side that served with the 4th S.C. and 6th S.C. Cav.
