Private McKinney was discharged for disability in October of 1861.
Permon died sometime before 1891 because his wife Rebecca filed for a widows pension. She would later marry Milton Huffman.
There is a "ermon McKinney" recorded buried in the Fairview Cemetery located in Randolph County Indiana. There is a very good chance it is the man from the 19th Indiana.
