Curious about your Walker/Meyer line. Am researching these same surnames, but mostly for Highland/Greene Co. OH. Believe there is a strong possibility that relatives were in Brown/Clermont as well. Wonder if your Meyer name has changed as the marriage record for the above states:
14 Feb 1850 (date of notice in the Clermont Courier) Married: On the 6th inst, by the Rev. Mr. Spofford, Dr. John E. Myers, of Goshen to Miss Hannah B. Walker, of Williamsburg.
Would be interested in sharing info with you.
