Leuillen History, Family Crest & Coats of Arms
The Leuillen 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." 
Early Origins of the Leuillen family
The surname Leuillen 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." 
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."

Leuillen Spelling Variations
Welsh surnames are relatively few in number, but they have an inordinately large number of spelling variations. There are many factors that explain the preponderance of Welsh variants, but the earliest is found during the Middle Ages when Welsh surnames came into use. Scribes and church officials recorded names as they sounded, which often resulted in a single person's name being inconsistently recorded over his lifetime. The transliteration of Welsh names into English also accounts for many of the spelling variations: the unique Brythonic Celtic language of the Welsh had many sounds the English language was incapable of accurately reproducing. It was also common for members of a same surname to change their names slightly, in order to signify a branch loyalty within the family, a religious adherence, or even patriotic affiliations. For all of these reasons, the many spelling variations of particular Welsh names are very important. The surname Leuillen has occasionally been spelled 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 Leuillen family
The Welsh migration to North America in the late 19th and early 20th centuries contributed greatly to its rapid development. These migrants were in search of land, work, and freedom. Those Welsh families that survived the long ocean journey were critical to the development of new industries and factories, and to the quick settlement of land. They also added to an ever-growing rich cultural heritage. A search of the immigration and passenger lists has shown a number of people bearing the name Leuillen: Ann Flewelling who purchased land in Virginia in 1643 and in the same year Thomas Flewelling settled in a nearby piece of property.
