Etymology of Sien

What does the name Sien mean?

The Sien surname was a Norman habitation name, derived from when families lived at St. Clai-sur-Elle in La Manche and in St-Clair-L'Evêque in Calvados, Normandy where the site of the seignorial castle is still discernible. 1

Sien Coat of Arms Creation

The Gordons now claim to be " Cocks of the North," a title which the Sinclairs of Caithness, who have a Gallic cock (rooster) as their crest, say ought to be theirs. Why it should be called " Gallic " they can scarcely explain, unless it be that this clan is of French origin.

The senior branch of the Sinclair Clan and several of the collateral branches carry, on the authority of the Lyon Office, a " Cock proper " as crest. The crest was not always carried as at present like a proper barn-door fowl. In 1566 George Sinclair, fourth Earl of Caithness, used arms quartered with those of his wife, Lady Elizabeth Graham, daughter of the Earl of Montrose, and in these the cock is shown full face with wings extended. The family tradition is that the Earls of Caithness, until the battle of Flodden, were " Cocks of the North." After that battle the clan became a very small one, as all the fighting men were killed, and the Duke of Gordon then assumed the designation.

The cock is an emblem of watchfulness and mirth after victory. It was placed on the summit of churches as an emblem of vigilance, or as a warning against St Peter's sin. 2

Early Origins of the Sien family

The surname Sien was first found in the barony of Roslyn, Midlothian where King Alexander I of Scotland granted a parcel of land to William de Sancto Claro in 1162. They were originally from St Clare, Pont d'Eveque, Normandy, and are descended from Walderness Compte de Saint Clare who arrived in England with William the Conqueror.

"Wace mentions the Sire de St. Clair at Hastings. This was Richard de St. Clair who held lands, Suffolk, 1086, 3" 4 The Domesday Book also notes that Britel de St. Clair, brother of the aforementioned Richard de St. Clair held lands in Somerset. Britel's son William de St. Clair held lands in Dorset in 1130.

Despite these early records in England, the name is more often than not associated with Scotland. For it is there that the name excelled both in numbers and power. "The first Sinclairs in Scotland appear to have been vassals of the great territorial magnates, de Morville. Their first possession in Scotland was the barony of Roslin, near Edinburgh, which they held in the reign of David I (1124-1153). The earliest bearers of the name appear in charters connected with the abbeys of Dryburgh and Newbattle, the Hospital of Soltre (now Soutra in Midlothian), the church of Glasgow, etc." 5

Sir Henry Sinclair fought with King Robert the Bruce at Bannockburn, and helped assure the independence of the Scottish Kingdom. Sir Henry's son married Isabel, the heiress of the earldom of Orkney, and their son became the senior Earl of Norway. The Clan achieved great status having married into both Norwegian and Scottish royalty.

Back in England, the name prospered as well as The Hundredorum Rolls of 1273 confirms: John de Sanet Claro in Suffolk; Robert de Sancto Claro in Somerset; and William de Sancto Claro in Kent. 6

Over in Somerset, from the first listing above, Richard Seinteclere and William Seyncler were both listed in Kirby's Quest. 7

The Sien 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: Commit thy work to God
