The Cartington Castle Cemetery is located on the estate near the front side of the Castle. Known Burials from the late 14th Century until the late 17th Century. 

Cartington Castle, a ruinous, partly restored medieval English castle in the hamlet of Cartington, 2 miles (3.2 km) north-west of Rothbury in the county of Northumberland, England, looking down on the River Coquet. It is a Scheduled Ancient Monument and a Grade I listed building.

The history of Cartington can be traced on the strength of its placename to the Early Middle Ages. The area's first recorded landowner was Ralph Fitz-Main who held it in 1154. Cartington is not recognized until the Pipe Roll dated 1233 as Kertindon, a holding of the King's Forester by Ralph Fitz-Main. This family remained significant in the township, but increasingly land within it was held by another family, called the de Beaumains (an extinct surname), who built a manor and in time changed their name to Cartington after the placename, and eventually took over the manor here. In the late 14th century John Cartington I added a Peel Power. This was extended to include a great hall, and a fortified tower that defended the courtyard, by John Cartington III in 1442 when he was granted a license to crenellate his home.The Cartington family remained influential until the death of John de Cartington in 1494, after which it passed through marriage to Sir Edward Radcliffe of Derwentwater. In November 1515 Margaret, Queen of Scots, with her baby daughter Margaret stayed here on her journey south from Harbottle Castle. Nearly ten years later, Lord Dacre stationed his troops here on a march north to join the Earl of Surrey. It finally passed through marriage to Sir Edward Radcliffe of Derwentwater. In 1601 it transferred as the dowry of Mary Radcliffe on her marriage to Roger Widdrington. The Widdrington's espoused the Royalist cause in the English Civil Wars, with Roger Widdrington supporting the King's Army during the Bishops' Wars of 1639, and his son, Sir Edward Widdrington, raised a brigade of two thousand foot and two hundred horse which served under the Marquis of Newcastle. Cartington remained in his wife's hands, and the family remained loyal to the King's cause, for in 1648 a Major Sanderson, serving under Parliament, made a raid across Northumberland to take by surprise a scattered remnant of a Royalist force, with the final action being at Cartington Castle, where Sir Richard Tempest was surprised and laid siege to for two hours before being captured. Subsequently the family were sequestered for their support of the King; being fined £400 for giving intelligence to the King's party and with Cartington Castle being slighted to prevent its further use.

Lore: It is said the de Beaumains are direct descendants of Sir Prince Gareth, Knight of the Round Table, son of King Lot and Morgause (King Arthur's sister) in the Arthurian legend. He was also known as "Beaumains."
