The Trehearn 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 Trehearn family

The surname Trehearn 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.
