Origin of the Name Thomason
family history was found in the allfamilycrests.com archives. Thomason is a baptismal name meaning 'the son of Thomas'. Variants of this name include Tomason, Thomassen and Thomas. This name is usually of Welsh descent spreading to Ireland, Scotland and England in early times and is found in many mediaeval manuscripts in these countries. Examples of such are a Roger Thomas of Cambridge, a Richard Thomas of Suffolk, and a Walter Thomas of Wiltshire, who were all recorded in the 'Hundred Rolls', England, in the year 1273. A Thomas Filius attested a deed in Scotland in the thirteenth century. An Adam Thomasson and a Johannes Thomasson were recorded in the 'Poll Tax' of the West Riding of Yorkshire in the year 1379. This is one of the most popular names in Britain and is especially found in Wales and Cornwall. In Ireland it is principally found in Dublin and Belfast where it was introduced from England centuries ago. Some Gaelic families who changed their name to MacThomas may have also anglicized their name as Thomason.
The Thomason coat of arms came into existence centuries ago. The process of creating coats of arms (also often called family crests) began in the eleventh century although a form of Proto-Heraldry may have existed in some countries prior to this. The new art of Heraldry made it possible for families and even individual family members to have their very own coat of arms, including all Thomason descendants.
