The Mergen name is Celtic in origin, arising from the ancient Britons of Wales. It comes from the Old Welsh personal name Morcant, composed of the Welsh elements "mor," meaning "sea," and cant meaning "circle."

Early Origins of the Mergen family

The surname Mergen was first found in Caernarvonshire (Welsh: Sir Gaernarfon), a former county in Northwest Wales, anciently part of the Kingdom of Gwynedd, and today divided between the unitary authorities of Gwynedd and Conwy. The surname is derived from the "Welsh personal name of high antiquity. The founder of the Pelagain heresy, in the fourth century, was a true Welshman and a monk of Bangor. His name was Morgan, which signifies 'Of the Sea' and this was correctly Latinized Pelagius. The Morgans of Golden Grove, co. Flint, descend from Marchudd ap Cynan, founder of the eighth noble tribe of North Wales and Powys. " 1

Mergen Spelling Variations

Compared to other ancient cultures found in the British Isles, the number of Welsh surnames are relatively few, but there are an inordinately large number of spelling variations. These spelling variations began almost as soon as surname usage became common. People could not specify how to spell their own names leaving the specific recording up to the individual scribe or priest. Those recorders would then spell the names as they heard them, causing many different variations. Later, many Welsh names were recorded in English. This transliteration process was extremely imprecise since the Brythonic Celtic language of the Welsh used many sounds the English language was not accustomed to. Finally, some variations occurred by the individual's design: a branch loyalty within a family, a religious adherence, or even patriotic affiliations were indicated by spelling variations of one's name. The Mergen name over the years has been spelled Morgan, Morgen, Morgain, Morgaine and others.
