I am the great grandson of Private Joseph Frank Newbill of Harrison County, Indiana. He enlisted January 28, 1863, in Company D, 13th Indiana Cavalry, at Corydon, Harrison County, Indiana.
He lived In Mississippi and Texas after the war. He died in Jones County, Texas, and is buried at Fort Phantom Hill. His monument lists his initials and last name and is marked that he was a Civil War veteran. Family oral tradition was that he was underage, lied about his age, and was a substitute for another man.
I have not been able to confirm that he was a substitute. Several rosters also have an incorrect spelling showing Newbell instead of Newbill.
Anyone researching the Joseph Frank Newbill family, or Company D, 13th Indiana Cavalry, I would welcome contact, to share what little information that I have.
