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

Early Origins of the Blethan family

The surname Blethan 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

Blethan 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 Blethan have included Blevin, Blevyn, Ap Blethyn, Ap Plethyn, Plethen, Blethin, Blethen, Blevins and many more.
