The Trehaurn surname comes from the ancient Welsh personal name Trahern. Some instances of the surname are derived from the name of the settlement of Trehane in Cornwall.

Early Origins of the Trehaurn family

The surname Trehaurn was first found in Flintshire (Welsh: Sir y Fflint), a historic county, created after the defeat of the Welsh Kingdom of Gwynedd in 1284, and located in north-east Wales, where they held a family seat at Trehaverne (Tregavran) which was referenced in the Domesday Book.

This area is now known as Kenywn and is a civil parish in Cornwall. Kenwyn is now regarded as a suburb of the city of Truro and gives its name to one of three rivers that flow through the city. However, the surname is believed to be descended from Traherne (Trahaearn ap Caradog) son of Caradoc, Prince of North Wales in 1073. 1

Today Trehan is a hamlet near Saltash in Cornwall, England.

Trehaurn Spelling Variations

Although there are comparatively few Welsh surnames, they have a great many spelling variations. Variations of Welsh names began almost immediately after their acceptance within Welsh society. In the Middle Ages, it was up to priests and the few other people that recorded names in official documents to decide how to spell the names that they heard. Variations that occurred because of improper recording increased dramatically as the names were later transliterated into English. The Brythonic Celtic language of Wales, known by natives as Cymraeg, featured many highly inflected sounds that could not be properly captured by the English language. Spelling variations were, however, also carried out according to an individual's design: a branch loyalty within the family, a religious adherence, or even patriotic affiliations were all indicated by the particular variation of one's name. The spelling variations of the name Trehaurn have included Traherne, Trahern, Treherne, Trehern, Traherne, Trahairn, Trahearne, Trahane, Trahan, Trehearn, Trahearn, Trehane and many more.

Migration of the Trehaurn family

Many Welsh joined the great migrations to North America in the late 1800s and early 1900s. Like their Scottish and Irish neighbors, many Welsh families left their homeland hoping to find hope and prosperity in a land that the English did not exercise a tight rule over. Those Welsh immigrants that successfully traveled to North America went on to make significant contributions to the rapid development of both Canada and the United States in terms of the settling of land and the establishment of industry. They also added to the rich cultural heritage of both countries. An examination into the immigration and passenger lists has discovered a number of people bearing the name Trehaurn: Samuel Traherne who settled in Jamaica in 1664; Charles and Margueritte Trahan settled in Maryland in 1763; John Trehearne settled in Virginia in 1622.
