The name of Mervyn is Celtic in origin, arising from the ancient Britons of Wales. The name's specific origins were derived from the Welsh personal name Mervin, which originally took the form Merlin. The magician Merlin plays an important role in Arthurian legend and is given the attributes of a Celtic druid. He figures prominently in early Welsh writings, and the first full-fledged treatment of him is given in the Libellus Merlini (Little Book of Merlin), a Latin tract written by Geoffrey of Monmouth c. 1135.

Early Origins of the Mervyn family

The surname Mervyn was first found in Wiltshire, where this distinguished Welsh family claim descent from Mervyn Vrych, (Merfyn Frych 'Merfyn the Freckled', Merfyn ap Gwriad 'Merfyn son of Gwriad', Merfyn Camwri 'Merfyn the Oppressor') an 11th century Lord of Anglesey, who settled in Wiltshire on the English Welsh border. He is thought to have died around 844 and was King of Gwynedd from around 825 to his death. He came from a long line of nobility.

Llywelyn ap Merfyn (died 942) was King of Powys, son of Merfyn ap Rhodri, and grandson of Rhodri the Great. His father, Merfyn ap Rhodri (died c.900) was also King of Powis (878-900.) Mystery surrounds his death. Some believe he died due to the incursion into Anglesey by the Viking Ingimundr. Others believe he lost his realm to an invasion by his brother Cadell, King of Ceredigion.

All trace back to Rhodri ap Merfyn (c. 820-878), later known as Rhodri the Great (Welsh: Rhodri Mawr), who succeeded his father, Merfyn Frych, as King of Gwynedd in 844. He is referred to "King of the Britons" by the Annals of Ulster and later as the "King of Wales."

Mervyn Spelling Variations

Although there are not an extremely large number Welsh surnames, there are an inordinately large number of spelling variations of those surnames. This variety of spellings began almost immediately after the acceptance of surnames within Welsh society. As time progressed, these old Brythonic names were eventually were recorded in English. 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 Mervyn has seen various spelling variations: Mervyn, Mervin, Mervyng, Merwin and others.

The Mervyn Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: De Dieu tout
Motto Translation: From God everything.
