Seisylt History, Family Crest & Coats of Arms
Seisylt is an ancient Norman name that arrived in England after the Norman Conquest of 1066. The Seisylt family lived in Devon. The name refers to the family's former place of residence, St Cecile, a Norman area of Flanders. 
Cecilia or Cecily (1469-1507), was "the third daughter of Edward IV, was born towards the end of 1469. At the age of five she was betrothed by proxy to James, the eldest son of James III of Scotland, and arrangements were soon made by which her dowry of twenty thousand marks should be paid by yearly installments. " 
Early Origins of the Seisylt family
The surname Seisylt was first found in Devon where they are "probably a branch of the Counts of Gand, whose arms (barry) it bears, with escutcheons charged with the lion rampant of Flanders. The arms are still borne in Flanders by a family of the same name."  Maurice de Cassel was probably one of the first to be listed in England during the reign of William I. His son, Robert de Kessel or Ciselle, assisted Robert Fitz-Hamon in the conquest of Glamorganshire in 1093. 
Saissil was recorded in Hertfordshire in the Domesday Book of 1086.  Later in Shropshire, Seisil was listed in the Pipe Rolls of 1188. Mononym names were quite common at this time. By 1205, William Seisel was listed in the Pipe Rolls of Hertfordshire and later again, William Seysel was found in the Subsidy Rolls for Worcestershire in 1275. 
Another reference claims "the family, doubtless of Norman origin, can be traced to Robert Sitsilt, who in 1091 assisted Robert Fitz-Hamon in the conquest of Glamorganshire."  Conflicting data is quite common with early records such as these. Continuing on: "from his descendant [Robert Kessel or Robert Sitsilt] Walter de Alterens, living 1165, descended the noble house of Cecil." 
Further to the north, in St. Martin's in Northamptonshire a later branch of the family was found. "The church [of St. Martin's] is a handsome structure in the later English style, erected by a bishop of Lincoln in the fifteenth century, and contains monuments to several members of the Cecil family, including one to Lord Treasurer Burghley, whose ancient mansion in the immediate neighbourhood, Burghley House."

Seisylt Spelling Variations
Norman surnames are characterized by a multitude of spelling variations. The frequent changes in surnames are largely due to the fact that the Old and Middle English languages lacked definite spelling rules. The introduction of Norman French to England, as well as the official court languages of Latin and French, also had pronounced influences on the spelling of surnames. Since medieval scribes and church officials recorded names as they sounded, rather than adhering to any specific spelling rules, it was common to find the same individual referred to with different spellings. The name has been spelled Cecil, Cecill, Cecyll, Cyssel, Cessell, Sitsilt, Sicelt, Seycil and many more.

Migration of the Seisylt family
Many English families emigrated to North American colonies in order to escape the political chaos in Britain at this time. Unfortunately, many English families made the trip to the New World under extremely harsh conditions. Overcrowding on the ships caused the majority of the immigrants to arrive diseased, famished, and destitute from the long journey across the stormy Atlantic. Despite these hardships, many of the families prospered and went on to make invaluable contributions to the development of the cultures of the United States and Canada. Early North American immigration records have revealed a number of people bearing the name Seisylt or a variant listed above: John Cecill who settled in Barbados in 1663; William Cecill arrived in Pennsylvania in 1682; later Joseph Cecil arrived in New York in 1823; and Thomas Cecil arrived in Philadelphia in 1866..
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: Cor unum via una
Motto Translation: One heart one way.
