In the grand scheme, a single company is a relatively small focal point. You may want to broaden your query to the regimental or even brigade scope.
Sadly, many folks do not know of, or have little interest in their family’s roll in American history.
On a personal note, I had 4 gr-great uncles in Company F, 42nd Virginia Infantry. One died in 1862. One received a medical discharge for tuberculosis. Two were released from Point Lookout a few weeks before the Surrender. While it is true that only 44 surrendered at Appomattox, hundreds of men who served in the 42nd VA survived the war.
