As far as post-war information on Alfred Thayer goes, the prominent theme is the grudge match between him and the pension office. Ever since he was no longer active in the military, he was in a constant battle to raise his pension to an amount that he felt was just.

There is very little information regarding his personal life. After the war he married Mary Jane Thayer in 1867. With his wife, he had two sons, Edward and Willard Thayer. He predominantly lived in Jackson, Michigan, but later moved to Decatur, Illinois. I have not been able to figure out was Thayer’s occupation was.

During the war, Thayer was shot in the shoulder, which continued to ail for him for the rest of his life. Doctors claimed that his arm was essentially paralyzed and was equivalent to the loss of his hand and arm.
