Show ContentsFlewillyn History, Family Crest & Coats of Arms

The Flewillyn surname is derived from the Welsh personal name Llewellyn, which was also spelled Llywelin. This name is often explained as meaning lion-like, but is in fact probably derived from the Welsh word "llyw," which means leader. The Welsh double l was a constant source of trouble to English speakers, and was often translated "f." "A very ancient Welsh personal name, borne by many princes and magnates of Celtic origin." 1

Early Origins of the Flewillyn family

The surname Flewillyn was first found in Pembrokeshire (Welsh: Sir Benfro), a county in south-west Wales, anciently part of the Welsh kingdom of Deheubarth. The most famous and oldest reference of the name was Dafydd ap Llywelyn (c.1212-1246), Prince of Gwynedd from 1240 to 1246, the first ruler to claim the title Prince of Wales. His father was Llywelyn the Great (Welsh: Llywelyn Fawr) (c. 1172-1240), Prince of Gwynedd in north Wales who eventually became ruler over most of Wales. "Davydd ab Llewelyn died at Aber, about 1246, and was buried in the abbey of Conway." 2

Over in Aberedow, South Wales "Llewelyn's Cave, is said to have been occasionally used as an asylum by that brave, but unfortunate, prince, Llewelyn ab Grufydd, the last royal defender of Welsh liberty and independence, against the overpowering army of Edward I." 2

Flewillyn Spelling Variations

The Welsh have an extremely large amount of spelling variations of their native surnames to their credit. It was up to the priest or the scribe taking the official records to determine how the spoken name was to be made literal. As time progressed, the old Brythonic names of Wales were recorded in English, which was especially problematic since the English language had extreme difficulty recording the highly inflected sounds of Cymraeg. 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 could be indicated by spelling variations of one's name. The spelling variations of the name Flewillyn have included Flewelling, Flewellen, Llewellen, Llewillan, Llewellyn, Alewellyin, Flewellyn, Flywillan, Fleuellan, Llewallin, Llewallyn, Flewellan, Flewellin, Llewellan, Lewellin, Lewellen, Lewillan, Lewellyn, Lywellen, Lywellin, Lewallin and many more.

Migration of the Flewillyn family

North America in the 1800s and 1900s saw the arrival of many Welsh people hoping to share in the wealth of land, work, and freedom that they felt North America held. Those who made the journey often attained those expectations, but only through an enormous amount of hard work, perseverance, and often a bout of good luck. These immigrants helped contribute to the growth of industry, commerce, and culture of both Canada and the United States. Discovered in the immigration and passenger lists were a number of people bearing the name Flewillyn: Ann Flewelling who purchased land in Virginia in 1643 and in the same year Thomas Flewelling settled in a nearby piece of property.
