Baron de Villiers, of Wynberg in the Cape of Good Hope Province and the Union of South Africa, is a title in the Peerage of the United Kingdom.
[1] It was created on 21 September 1910 for the prominent South African lawyer and judge John de Villiers.
The 3rd Baron graduated from Magdalen College, Oxford and worked as a barrister in Auckland, New Zealand.
[2] As of 2010[update], the title is held by his great-grandson, the fourth Baron, who succeeded his father in 2001.
But the pronunciation which is used by English-speaking South Africans, and which I myself use, would be written duh vil'yers.
