Etymology of Blevyn

What does the name Blevyn mean?

From the Celtic land of Wales came the name of Blevyn. This name initially evolved from the Welsh personal name Blethyn.

Early Origins of the Blevyn family

The surname Blevyn was first found in Denbighshire (Welsh: Sir Ddinbych), a historic county in Northeast Wales created by the Laws in Wales Act 1536, where Meredith Ap Blethyn was Prince of North Wales in the 11th century. William the Conqueror seized Prince Meridith's castle at Oswestry in Shropshire after 1066 but he retained his Welsh estates. 1 2

"At the Survey we see that King William was Lord of this manor (Mileham), but soon after Alan, son of Flaald, obtained it by the gilt of William the Conqueror; also the castle of Oswaldstrey in Shropshire, which belonged to Meredith ap Blethyn, a Welshman or Briton." 3

Dafydd ap Bleddyn (died 1346), also known as David ap Blethin, was the Welsh Catholic Bishop of St. Asaph in Wales from 1315 to 1346.

This process was problematic in that many of the highly inflected sounds of the native language of Wales could not be properly captured in English. Some families, however, did decide to modify their own names to indicate a branch loyalty within the family, a religious adherence, or even a patriotic affiliation. The name Blevyn has seen various spelling variations: Blevin, Blevyn, Ap Blethyn, Ap Plethyn, Plethen, Blethin, Blethen, Blevins and many more.
