The ancestors of the bearers of the Mostyn surname lived in or near the Welsh settlement of Mostyn in Whitford. The surname Mostyn belongs to the category of habitation names, which are derived from pre-existing names for towns, villages, parishes, or farmsteads.

Early Origins of the Mostyn family

The surname Mostyn 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 were descended from one of the fifteen noble tribes of Wales. In the 12th century they were Lords of the Manor of Mostyn, seated at Mostyn Hall. At the taking of the Domesday Book in 1086 Mostyn, was held by Robert of Rhuddlan from whom they may also be conjecturally descended. Another branch of the family was found in Moston, Cheshire. "The manor, in old records "Moreston," was given about 1125 to the convent of St. Werburgh, under which an estate was held here by a family who took their name from the township." [1]

Mostyn 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 Mostyn has seen various spelling variations: Mostyn, Mostin, Mostyne, Mosten, Mostine and others.

The Mostyn 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: Auxilium meum a Domino
Motto Translation: My help is from the Lord.
