The first ancestor I found a record of who served in the Civil War was when I visited the battlefield at Gettysburg. I was reading the names on the Pennsylvania memorial and found his name engraved on one of the plaques. Later, while I was shopping, I found the address of a woman in Virginia who would search for records at the National Archives for a reasonable fee. I submitted the guys name and unit info and received copies of his service record. Since that time, I have also received copies of records for two more of my ancestors. There are many more I've been told were enlisted, but have to yet verify it by documentation.
