Yes. Nancy Patch was his widow and is on his Pension Index Card and the Special Veterans Census 1890 . She was born Jones, married Earl, then Patch, then Boorn.
According to the Michigan Death Records, Eli Earl died at 33 of Delerium Tremens. He was a saloon keeper. If you look at the list of battles he was engaged, I can imagine I'd take to drink as well!
Look it over and if you see anything missing or redundant, let me know.
