Early Origins of the Sleyne family

The surname Sleyne was first found in Wales where Robert FitzStephen (d. 1183?), was "one of the original Norman conquerors of Ireland. He was the son of Stephen, constable of Aberteivi (Cardigan), and of Nesta, daughter of Rhys ab Tewdwr, king of South Wales. In 1157, Robert followed Henry II's expedition into North Wales, and narrowly escaped the ambush in which his half-brother, the king's son, was slain. His inheritance included Cardigan,_Ceredigion' target='_blank'>Cardigan and Cemmes, and he became constable of Cardigan town in succession apparently to his father. In November 1166 he was betrayed by his own men into the hands of his cousin, Rhys ab Gruffydd, with whom he was then at war. In the spring of 1169 Fitzstephen, with his half-brother, Maurice Fitzgerald (d. 1176), landed in Ireland at Baganbun or Bannow, near Wexford. They were accompanied by thirty knights, sixty men-at-arms, and three hundred Welsh foot soldiers." 1

William FitzStephen (d. 1190?), was the biographer of Becket, and styled himself the archbishop's 'concivis.' He was in the closest connection with Becket for ten years or more, as his 'clericus et convictor.' 1

Sleyne Spelling Variations

It is only in the last few hundred years that the English language has been standardized. For that reason, Anglo-Norman surnames like Sleyne are characterized by many spelling variations. Scribes and monks in the Middle Ages spelled names they sounded, so it is common to find several variations that refer to a single person. As the English language changed and incorporated elements of other European languages such as Norman French and Latin, even literate people regularly changed the spelling of their names. The variations of the name Sleyne include Fitzstephen, Fitzsteven, Sleyne, Sliney, Sloyan, Sline and many more.

Migration of the Sleyne family

Faced with the chaos present in England at that time, many English families looked towards the open frontiers of the New World with its opportunities to escape oppression and starvation. People migrated to North America, as well as Australia and Ireland in droves, paying exorbitant rates for passages in cramped, unsafe ships. Many of the settlers did not make the long passage alive, but those who did see the shores of North America were welcomed with great opportunity. Many of the families that came from England went on to make essential contributions to the emerging nations of Canada and the United States. Some of the first immigrants to cross the Atlantic and come to North America carried the name Sleyne, or a variant listed above: the name represented in many forms and recorded from the mid 17th century in the great migration from Europe. Migrants settled in the eastern seaboard from Newfoundland, to Maine, to Virginia, the Carolinas, and to the islands..
