The Welsh name Wiliam is a patronymic surname derived from the personal name William, which is in turn derived from the Old German names Willihelm and Willelm (the Norman French version was Guillaume). Following the Norman Conquest of 1066, William became the most popular personal name in Britain for a time.

Early Origins of the Wiliam family

The surname Wiliam was first found in Breconshire and Monmouthshire on the English/Welsh border, where they are traditionally believed to be descended from Brychan Brecheiniog who was Lord of Brecknock at the time of King Arthur of the Round Table.

The mediaeval seat of the ancestors of the Wiliam family was at Llangibby Castle in County Monmouth. More recently, the family is descended through Rhys Goch, the red haired Lord Ystradyw from Caradog Vreichvras.

One of the first records of the name was listed as Robertus filius Willelmi 1 which was listed in the Domesday Book. 2 Other early records include Richard Williams who was listed in the Hundredorum Rolls of 1279 and John Wylyam who was listed in the Subsidy Rolls of Sussex in 1296.

Wiliam 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 Wiliam has seen various spelling variations: Williams, Quilliams, Guilliam, Guilliams and others.

The Wiliam 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: Ensuivant la verite
Motto Translation: By following the truth.
