Show ContentsThomason History, Family Crest & Coats of Arms

The origins of the ancient name Thomason belong to that rich Celtic tradition that comes from Wales. This surname was derived from the Aramaic personal name Thomas, which means twin. Prior to the Norman Conquest, this name was rarely found, but by the 13th and 14th centuries, it became extremely common in Britain. The surname Thomason features the patronymic suffix -son, which superseded other patronymic suffixes in popularity by the 14th century and was most common in the north of England.

Early Origins of the Thomason family

The surname Thomason was first found in Cheshire, where they held a family seat from very ancient times before and after the Norman Conquest in 1066.

Thomason Spelling Variations

There are relatively few surnames native to Wales, but they have an inordinately large number of spelling variations. Early variations of Welsh surnames can be explained by the fact that very few people in the early Middle Ages were literate. Priests and the few other literate people were responsible for recording names in official documents. And because most people could not specific how to properly record their names it was up to the individual recorder of that time to determine how a spoken name should be recorded. Variations due to the imprecise or improper recording of a name continued later in history when names originally composed in the Brythonic Celtic, language of Wales, known by natives as Cymraeg, were transliterated into English. Welsh names that were documented in English often changed dramatically since the native language of Wales, which was highly inflected, did not copy well. Occasionally, however, spelling variations were carried out according to an individual's specific design: a branch loyalty within the family, a religious adherence, or even patriotic affiliations could be indicated by minor variations. The spelling variations of the name Thomason have included Thomason, Thomasson, Thomerson, Thomoson and others.
