Actually, it was Irvin Moody's sister that took care of his burial and memorial (I assume his body was sent back from the battlefield).
Little is known of Irvin Moody's family. In the 1850 census he is living with his mother and sister in Philadelphia. I believe that Irvin and his sister Orrilla were educated. Irvin's trade was bookkeeper and I believe Orrilla was teaching.

In 1853, we find a notation in a book - Public school district of State of Pennsylvania (Philadelphia, Pa.) of a Orrilla Moody, assistant principal - No. 6.
By 1860, Irvin Moody had moved to Louisville, KY, occupation was bookkeeper. Indiana was a stone's throw away (across the Ohio River).

One of the towns that recruited for the 93rd Indiana Inf. was Madison, IN. Madison was 50 miles up the Ohio river.
By 1860, Orrilla had married Joseph Whitehead of Trenton, NJ. Joseph Whitehead and his five brothers were in the Woolen, then the Rubber business.
