Show ContentsTrefor History, Family Crest & Coats of Arms

The Trefor family name comes from the name of either of the Welsh settlements called Trevor in Denbigh and Anglesey. As such, the surname Trefor belongs to the category of habitation names, which are derived from pre-existing names for towns, villages, parishes, or farmsteads.

Early Origins of the Trefor family

The surname Trefor was first found in Herefordshire, where Tudor Trevor was Lord of Hereford, Wittington, and both Maelors, founder of the Tribe of the Marches. He was son of Ynyr Ap Cadforch, Lord of both Maelors in Powys, a Baron of Powys.

Trevor Hall is a large grade mansion standing in 85 acres (35 hectares) of parkland at Trevor, near Llangollen, Denbighshire, Wales. The estate has been in the family since medieval times and was at one time the home of Bishop John Trevor (died 1357.)

There was always a close relationship with people of Wales and Cornwall; so it is not surprising to find an early reference to the family there. "The manor of Trevear [in the parish of Gorran] was formerly the property, and the mansion the residence of a family of this name. Tonkin says, that the mansion of Sir Henry Trevear was standing so late as the year 1736. From this family it passed to the Scawens, and it is now the property of Thomas Graham, Esq." 1

Trefor 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 Trefor have included Trevor, Trefor and others.
