The title Lord Polwarth, of Polwarth in the County of Berwick, was created in the Peerage of Scotland in 1690 for Sir Patrick Hume of Polwarth, 2nd Baronet. In 1697, Hume was granted a second creation of the Lordship, along with the Earldom of Marchmont. Upon the death of the third Earl, however, the creations of 1697 became dormant (unclaimed), while the 1690 Lordship passed to Anne Anstruther-Paterson.
Marchmont Care Centre is part of Sue Ryder Care - a national charity devoted to the care of people with a wide range of physical, psychological, social and spiritual needs.
Marchmont was built between 1750-54 for Hugh, third and last Earl of Marchmont.
Marchmont is registered to care for the young physically disabled and is establishing itself as a specialist centre for the care of people with neurological and genetic disorders, in particular Huntington's Disease.
