The Asquiths were originally a middle-class family from the West Riding of Yorkshire, England. They were members of the Congregational church, whose family name derived from the village of Askwith. The first prominent member of the family was H. H. Asquith, who was prime minister from 1908 to 1916. In 1925, Asquith was raised to the peerage as Earl of Oxford and Asquith. His great-grandson Raymond is the present Earl.
All of H. H. Asquith's seven children achieved some prominence in national affairs. By his first wife Helen Kelsall Melland (d. 1891), he had four sons and one daughter. All of the sons volunteered for the Front early in the war. The eldest son, Raymond, a barrister and poet, was killed in action in 1916. The second son, Herbert, was a poet who married Lady Cynthia Charteris, a writer and anthologist. The third son, Arthur, became a Brigadier. The fourth son, Cyril (1890–1954), became a Law Lord. The daughter, Violet (1887–1969) became a Liberal politician herself.
By his second wife, the former Margot Tennant, Asquith had two more children. His daughter Elizabeth (1897–1945) was a writer who married a Romanian prince, becoming Princess Antoine Bibesco. His youngest son Anthony (1902–1968) became a well-known film director.
