Yes and no. People would probably have been buried there, but their tombstones would likely have fallen apart, so new people would probably be buried there.

In some of the older cemeteries yes, it would be possible to find graves that old, especially if they belonged to persons of importance. After all there are far older graves of royalty that have survived. And here in America there are many cemeteries that have graves dating from the early 1800's to the late 1700's, particularly up north.

However, keep in mind that because England has so little land, they developed a habit of re-using graves and burying people together

That would depend on which area of England you would be looking. In many large cities, London in particular, you will find many gravestones dating from roughly 1710 onwards. Occasionally earlier varieties can also be found as these would have been people or families of note who could afford an expensive marker hence the reason they have lasted.

In more rural areas of England you can find graves that will date back to the early 16th and 17th centuries.

i dont think so. i live opposite a church and the graves are old (so the dates are faded), but they are not that old.

i assume in some big cities like London that were bombed in the war, the graves were destroyed so it depends where you look

also, when they run out of space, bodies are exhumed to put more down.
