I've sent copies (original image scan and one with transcription) of the letter by Rev. Denny to Mr. Martin for forwarding to you.
There were 4 Deatherage's in the 50th Virgina Infantry and you have them all listed in the roster in the back of your book. As I mentioned in my original post, Mathew Henry is my great grandfather and Sampson H. Deatherage was his younger brother. Emery Dent Deatherage and Leabon Hilary Deatherage were cousins of Mathew. All the Deatherages in the 50th were from Patrick County, Virginia.
Rev. Denny mentions that he recovered $38.00 from Sampson when he died and that this money would be delivered upon request. There are some documents in the Compiled Service Records which were submitted by Sampson's parents, William and Elizabeth Deatherage, to the Confederate government in application for these funds.
After Sampson was killed, Mathew re-enlisted - this time in the 8th Virginia Cavalry. It appears that he stayed with the 8th through 1864, and possibly though the end of the War. Mathew's youngest brother, John G. Deatherage, joined him in the 8th Cavalry in July of 1864 but was captured at the Battle of 3rd Winchester in September, 1864. He was sent to Camp Chase POW camp in Columbus, Ohio and died there in January, 1865.
Mathew Henry was the only son to survive the war. During reconstruction, he travelled with his cousins to Moniteau County, Missouri where other cousins had already set up homesteads. Mathew lived out the rest of his life in Missouri.
