Lots of my HARMAN ancestors are buried in the Odessadale Methodist Church cemetery. My father was David Hill Harman, who is buried in Alpharetta, Georgia . Are there still services at the Church ? ( Their pastor used to be a “circuit rider” who pastored several churches in the area.)

I hope to hear from someone ; I’d like to visit the Church again .
