Teresa Mary Nugent Freeman-Grenville, 13th Lady Kinloss (born 20 July 1957) is a Scottish peer.
She is the heir-general of Lady Catherine Grey, sister of Lady Jane Grey, briefly Queen of England after the death of King Edward VI, and has thus been suggested as a claimant to the throne of England.
Born at Tanga, Tanzania, she is the elder of the two daughters of Mary Freeman-Grenville, 12th Lady Kinloss, by her marriage to Dr Greville Stewart Parker Freeman, later Freeman-Grenville. She is a great-great-grand-daughter of Richard Plantagenet Temple-Nugent-Brydges-Chandos-Grenville, 3rd Duke of Buckingham and Chandos (1823–1889), who was also Lord Kinloss.
Upon his death, some of his titles became extinct, while others passed to cousins, and only this lordship of Kinloss was inherited by his eldest daughter, Lady Mary. Her great-grand-daughter the present Lady Kinloss is thus the senior heir-general of Edward Seymour, Viscount Beauchamp, the only son of Lady Catherine Grey, sister of Lady Jane Grey. In an alternative succession to the throne of England, based on the Will of King Henry VIII, Lady Kinloss inherits her mother's claim (never pursued) to the crown. Any claim may be bolstered in light of the DNA analysis of the remains of Richard III which took place in 2014. Also, her claim to the throne could be construed from a Yorkist perspective, based on her descent from Isabel of Cambridge, Countess of Essex.
She was educated Rye St Antony School (Headington, Oxford), then at York Art School, where she studied fashion. On 30 September 2012 she succeeded to the lordship of Kinloss on the death of her mother, which happened less than a year after the death of her brother, Bevil David Stewart Chandos Freeman-Grenville, Master of Kinloss (1953–2012).
Lady Kinloss lives at North View House, Sheriff Hutton, North Yorkshire, and has worked for National Milk Records since 1992. In Who's Who she states her recreations as dogs, keeping goats, and spinning and weaving.
The heir to the title is Lady Kinloss's younger sister, Hester Josephine Anne Haworth (born 1960), who married Peter Haworth in 1984 and has three sons.
