In th e Brown County,Ohio Marriage Records 1818-1850 There is this entry.
Gilkerson,William to Sarah Redenower, 24Aug,1849 Marriage performed by Squire Shelton,Aberdeen Ohio.
The listings performed by Squire Shelton are listed in the back of the book and may or may not have been recorded. The reason being Aberdeen,Ohio during that period of time was a "Gretna Green" meaning marriages were performed without too much attention of the laws in force at the time. For instance you could come across the river from Ky. and could avoid bonds or maybe questionable parental permission. Happy hunting. Eva
