Show ContentsSine History, Family Crest & Coats of Arms

The roots of the Sine family name are in ancient Scotland with the Viking settlers. Sine was derived from the Old English personal name Swein, which was originally derived from the Old Norse name Sveinn. This was one of the most common Scandinavian names in medieval Britain. Another source claims the name was an occupational name for someone "who acted as a servant or attendant; one who tended swine; descendant of Swain (young man, or boy servant)." [1]

Sweyn or Svein (d. 1014), was "King of England and Denmark, called Forkbeard, son of Harold Blaatand, King of Denmark, probably by his Queen Gunhild, though it was said that his mother was a Slav, a servant in the house of Palna-Toki, or Tokko, in Funen. " [2]

Earl Sweyn or Swegen (d. 1052), "the eldest son of Earl Godwin or Godwine and his wife Gytha, was early in 1043, when Edward or Eadward, called the Confessor, had become king, appointed to an earldom that was partly Mercian and partly West-Saxon, for it included Oxfordshire, Berkshire, Gloucestershire, Herefordshire, and Somerset. " [2]

Early Origins of the Sine family

The surname Sine was first found in Lanarkshire (Gaelic: Siorrachd Lannraig) a former county in the central Strathclyde region of Scotland, now divided into the Council Areas of North Lanarkshire, South Lanarkshire, and the City of Glasgow, from very early times.

Further south in England, the Hundredorum Rolls of 1273 listed early spelling of the family: John le Swein and Robert le Swein in Oxfordshire; and Geoffrey le Sueyn in Norfolk. The Yorkshire Poll Tax Rolls of 1379 lists: Robertus Swaynne. [3]

"The ancient name of Swain, which is now best represented in Lincolnshire, Leicestershire, Derbyshire, and Devonshire, was established in the form of Sweyn, rarely of Swayn, during the 13th century in Lincolnshire, Norfolk, Cambridgeshire, and Oxfordshire, being most numerous in the last two counties. " [4]

The Sine 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: Fidelitas
Motto Translation: Fidelity.
