After another long night of searching, I have added 4 new uncles to my master list of biological uncles and grandfathers who served in some capacity in the Civil War. (This excludes step-grandfathers, uncles by marriage, and any cousins--it is exclusively for close biological relatives.)
Tonight I added:
John Calvin Dooley - Served in the 19th Texas Infantry (CON) - He was the son of James Boyd Dooley and Frances Crump. He appears in the 1850 Census as Calvin Dooley. He marries Elizabeth M. Seago in 1856 in Cass County, TX, where he is found in the 1860 Census. He is in Titus County, Texas for the 1870 and 1880 Censuses and is supposedly buried in Morris County next to his wife. He was the brother of my 5th great grandmother, Emeline Pearl Dooley.
Beverly Ryland Jeter - Served in the 36th Virginia Infantry (CON) - He was the son of Sovereign Jeter and Matilda Vaughan. He drew a Confederate pension late in life. He was the brother of my 5th great grandfather, James Milton Jeter.
John Monroe "Jack" Mooney and William Jasper Mooney - They both served in Company K of the 20th Mississippi Infantry, as proven by their headstones and service records. They were sons of Reuben Mooney and Matilda Davis. They were brothers of my 3rd great grandmother, Mary Ann Frances Mooney.
I am very proud of all 81 of my uncles and grandfathers who served in the Civil War. Some deserted after just a few days, some were prisoners, and a handful died in various ways from being struck by lightning to dying in Camp Douglas.
