Just checking various sites, and while I don't have specific information on the ARNETT Family, I have visited the OAKLAND Cemetery (ca 2008). The folks there are nothing short of fantastic and very helpful. I couldn't find the grave I was looking for and they asked me to leave an address. About 6-8 months later, I received a letter from them with information on the probable grave location (very early part of the cemetery) and were apologetic that they couldn't give me the exact location.
