That fenced-off corner of the property
If you own a few acres anywhere between Hillsborough and the Eno River, there's a decent chance you've already found it: a small square of ground ringed by a rusted iron fence or a low fieldstone wall, maybe a dozen headstones leaning at odd angles under a stand of old cedar trees. Orange County has hundreds of these family cemeteries scattered across old farmland, some dating back to the 1700s, and most were never mapped or recorded anywhere official. You may be noticing right now that yours has gotten harder to see. Ivy, privet, and volunteer cedar seedlings grow fast here, and a plot that was clear ten years ago can be swallowed by underbrush in a single growing season.
This is common enough in this part of the Piedmont that it's worth understanding what you're actually looking at before you decide to mow it, fence it differently, or leave it alone.
What the clay soil and the seasons do to old graves
Orange County's red clay holds water in winter and cracks hard in a dry August. That freeze-thaw cycle and the swelling clay are why so many older headstones here lean, sink, or split along old fracture lines. A stone that was upright a generation ago may now be tilting several degrees, and the ground around it may have settled unevenly, sometimes enough to leave a shallow depression you can twist an ankle in if you're not watching your feet.
Heavy spring rain is the other thing to watch. Runoff from higher ground can wash soil away from foundations and footstones, especially on the sloped land common around Hillsborough. If you see exposed brick or stone footings that used to be below grade, or a fence post that's shifted, that's erosion doing its slow work, not vandalism, though it's worth checking for both.

What you can check yourself
You can walk the plot in spring before growth gets heavy and note which stones have shifted since last year. Photographs from the same angle each year are the easiest way to track slow movement. You can clear invasive vines and brush by hand, but avoid pressure washers, wire brushes, or bleach on the stones themselves. Older marble and soft sandstone markers common in this area are easily damaged by cleaning methods that would be fine on a modern granite stone.
You can also check with the Orange County Register of Deeds or the local historical society to see if the cemetery is already recorded. Many family plots in this county are legally protected even without a formal easement, and North Carolina law generally requires reasonable access be preserved for descendants, regardless of who owns the surrounding land now.
Where it stops being a do-it-yourself project
Resetting a fallen or badly leaning headstone is not a weekend project. The stones are heavier than they look, often set on foundations that have shifted underground in ways you can't see from the surface, and an amateur repair can crack a marker that's survived two centuries of Carolina weather. This is where it makes sense to bring in someone who works with cemetery preservation or monument repair specifically, rather than a general contractor.
If you're dealing with unmarked graves, suspected unrecorded burials, or any plan that involves moving soil near a known plot, that's also a point to stop and call in help. Ground-penetrating radar surveys and proper documentation exist for a reason, and disturbing unmarked graves, even accidentally, carries real legal weight in North Carolina.
If you're the one making arrangements now
Families dealing with a death often discover a cemetery question at the worst possible time, when there's a wish to be buried in an old family plot that hasn't been used in decades. If that's your situation, start early. Confirm the plot's legal status, check whether the access road or path is still usable after recent storms, and find out whether the local health department has any requirements for a burial ground that hasn't been active recently. A funeral home familiar with Orange County's older cemeteries can usually walk you through what's needed faster than trying to piece it together yourself under time pressure.
