As an example my Great-Grand father was a Civil War Veteran (13th-16th Ga. Calvary). He died in 1927. My Great-Grandfather fathered eleven sons and they have been deceased for several years. My mother is his youngest real granddaughter and she is 100 plus 3 months but still is able to live in the house that has been her home for over 60 years, but she too will soon join her relatives in the "old Camp Ground".
Mother was in her mid to late teens when her grandfather died and she has shared some wonderful stories of his Civil War experiences (He accompanied Gen. John H. Morgan on his first raid and his unit fought in Tenn, West Virginia, Virginia, Maryland, and in the Battle of Atlanta.) Needless to say, he never forgave the "Yanks" for Sherman's march through Georgia because his family's farm was located about 20 miles south of Sherman's route.
The records indicate that he never formally surrendered and after the war walked home from Bristol, Virginia after the war. Took him almost a year since he lived off the land and spent a few weeks with a comrade in arms.
God Bless his memory.
