His parents were first cousins as his mother was the eldest daughter, and heir of line, of the Hon. Harry Ker (from his great-grandfather's second marriage to Jean Drummond, who was also his paternal grandfather's younger sister). His maternal grandmother was Lady Margaret Hay, the only daughter of William Hay, 10th Earl of Erroll and Lady Anne Lyon (daughter of Patrick Lyon, 1st Earl of Kinghorne). After his grandfather died, Lady Margaret remarried to John Kennedy, 6th Earl of Cassilis.[2]
He lived in Golfer's Land on the Canongate (around 500m from the Law Courts in Edinburgh), as immediate successor to its builder, John Paterson. He died in this house and was buried to the east in Holyrood Abbey. After the Union of 1707 Golfers Land became the abode of lower classes and fell into disrepair.[3]
Bellenden died in March 1707 and was succeeded by his eldest son, John as the 3rd Lord Bellenden.[5] After his death, his widow married for the third time to Dr. Samuel Collins.[5]
Through his son William he was a grandfather to William Bellenden (1728–1805), who later became 7th Lord Bellenden in 1797 and the 4th Duke of Roxburghe in 1804.[11] Upon Williams death in 1805, the Lordship of Bellenden of Broughton became extinct.[5]
