Hi, I was wondering how I could go about finding cemetery records. Are they kept at the court house or library or at the cemetery itself? What I'm trying to find specifically is where the following information came from.

John Cephas Barker
b. May 11, 1861, d. October 2, 1947
(son of Walter Scott Barker &
America Barker Barker)

Where did they get the son of part to this? It's not on the tombstone. I thought is I could find out about cemetery records, I could find what I was looking for. Thanks for the help!
