Baron Bicester, of Tusmore in the County of Oxford, is a title in the Peerage of the United Kingdom.[2] It was created on 29 June 1938 for the banker Vivian Smith. As of 2018[update] the title is held by his great-grandson, the fifth Baron, who succeeded his first cousin once removed in 2016.
The Barons Bicester are related to the Barons Carrington. The first Baron Bicester's great-grandfather, John Smith MP (1767–1842), was the youngest brother of Robert Smith, 1st Baron Carrington. Also, John Smith's father, Abel Smith MP (1717–1788), had two elder brothers: George Smith (1714/15–1769), created a baronet in 1757 (see Bromley baronets), and John Smith (born 1716), the great-grandfather of Julian Pauncefote, 1st Baron Pauncefote.
