Llewellyn baronets
There have been two baronetcies created for persons with the surname Llewellyn, both in the Baronetage of the United Kingdom. One creation is extinct or dormant while one is extant.
The Llewellyn Baronetcy, of Bwllfa, Aberdare, in the County of Glamorgan, was created in the Baronetage of the United Kingdom on 31 January 1922 for David Llewellyn, a Welsh industrialist. He was notably Chairman of Welsh Associated Collieries. His first son, the second baronet, was High Sheriff of Glamorgan in 1950. His second son, the third baronet, was a well-known equestrian. As of 2021 the title is held by the latter's second son, the fifth baronet, who succeeded in 2009. He is a landscape gardener, gardening journalist, author and television presenter.
The Conservative politician Sir David Llewellyn was a younger son of the first Baronet and the younger brother of the second and third Baronets.
The Llewellyn Baronetcy, of Baglan in the County of Glamorgan, was created in the Baronetage of the United Kingdom on 20 January 1959 for Sir Godfrey Llewellyn, subsequently President of the National Union of Conservative and Unionist Associations. His son, the second Baronet, served as Lord Lieutenant of West Glamorgan from 1987 to 1994. On his death in 1994 the baronetcy became extinct or dormant.
