Greetings,

Good to hear of your concern. Yes, if no one speaks up, whoever owns the site will do what they want with it.

You mentioned Chatham County and NC, so I assume you mean Chatham County, NC. There is a Chatham County Historical Society with a mailing address in Pittsboro and their website says they are doing a cemetery "census" for the county.

Also check with the local history or reference librarian at the public library, as they may have some helpful suggestions.
