Somehow I missed your post, sorry!
I do have information on William J. Patton and Rachel Garrett and their family. I have Charles D. as Charles Dingee Patton. The Garrett and Patton family have several marriage points along with the Kelly family, but I have yet to untangle it all. Kelly's married into the Freeman family also. I have Freeman, Kelly, Strong, Thomas, Garrett and Patton. There are also others.
I have William's parents as Joseph Patton and Rachel Kelly and Rachel's parents as Henry Garrett and Nancy M. Johns.
I am descended from Rachel's brother William Garrett who married Mary Ellen Andrew. Their sister Melissa Garrett corresponded with William in the Civil War. Our family has original letters. William was wounded, recovered, came home, married, had three children and died of complications of his wounds. His son Orville Andrew Garrett was about 3 years old when his father died. His mother changed his name to William Orville Andrew Garrett.
Please contact me directly for what I have on the Patton, Kelly, Garrett firstname.lastname@example.org
