The arms are those of Damer impaling those of Sackville, as borne by Joseph Damer, born in 1717. He married in 1742 at Knole, Kent Caroline, daughter of Lionel Sackville, 1st Duke of Dorset. A Whig, he was M.P. for Weymouth 1741-1747, for Bramber 1747-1754 and for Dorchester 1754-1762. In 1753 he was created Baron Milton, an Irish creation and in 1762 created Baron Milton of Milton Abbey, Dorset. In 1792 he was created Viscount Milton and Earl of Dorchester. In politics he was one of the section of the Party that opposed Walpole. As Horace Walpole remarked, "Lord Milton, heir of Swift's old miser and usurer Damer, was the most arrogant and proud of men, with no foundation but great wealth and a match with the Duke of Dorset's daughter. His birth and parts were equally mean and contemptible." [Complete Peerage]

The magnificent silver-gilt toilet service presented by the Duke of Dorset to his daughter on her marriage to Joseph Damer was sold from the Collection of the late Antenor Patino, Christie's, New York, October 28, 1986, lot 12.
