Son of Thomas. The Welsh patronymic 'ap Tomas' compressed without taking the English genitive 's'. Thomas as a baptismal name spread across Wales through the medieval church — particularly through the Cistercian houses of Strata Florida and Strata Marcella — and the patronymic followed.
The history of Thomas
Thomas is among the top five Welsh surnames and is one of the few major patronymics that did not pick up the English-fashion genitive 's' (Jones, Williams, Davies, Edwards all did; Thomas mostly did not). Density is highest in west and south-west Wales.
The most internationally recognised bearer is Dylan Thomas (1914–1953), the Swansea-born poet of Under Milk Wood, Do Not Go Gentle into That Good Night, and Fern Hill — whose work, more than any single writer's, fixed the modern image of Welsh Nonconformist village life in the English literary imagination.
The R. S. Thomas line — Cardiff-born priest and poet (1913–2000), militantly Welsh-language nationalist for the second half of his life — is a counter-image: the Wales of the upland farms and the empty chapels, written in English under a sense of linguistic loss.
