Abiathar R. Barrett is the son of Thomas Augustus Barrett and Sarah Lenora Miller. He enlisted in the civil war and was killed in battle at the age of 22. We need more sources in his civil war service and genealogy. Does he have a gravestone? A pension?
Any help is appreciated
Note: I believe he was killed in battle May 31, 1862 in Fair Oaks, Fairfax, Virginia.
See The Battle of Seven Pines - May 31, 1862 shows the position of the 92nd N.Y
It appears the mother Sarah Barrett drew his pension need source link
