The name Roos is part of the ancient legacy of the early Norman inhabitants that arrived in England after the Norman Conquest of 1066. Roos was a Norman name used for a person who had the given name Andrew, which is derived from Anrias. The name may also be a nickname derived from the Old English word rouse, which means red or red-haired. [1]

Early Origins of the Roos family

The surname Roos was first found in Yorkshire, although there seems to be two distinct origins of this surname. This history discusses in detail the English/Scottish borders origin of the name. For this origin, the first reference of the name was Godfrey de Ross, a vassal of the de Morevilles, obtaining from Richard de Moreville the lands of Stewarton in Cuningham. [2]

This family of Ros or Ross came from Yorkshire. James de Ros, Reginald de Ross and Peter de Ross appear about the same time also as vassals of Richard de Moreville. These people are also listed as witnesses in his charters. The aforementioned Godfrey de Ross witnessed de Moreville's charter of Gillemoristun with Edulfus filius Utredi c. 1189. A few years later in 1205, Sir Godfrey de Rose, Arthur de Ross and Fergus de Rosse witnessed an agreement between the burgesses of Irvine and Brice of Eglunstone.

Robert de Ros or Rosse (d. 1227), "baron, was the son of Everard de Ros of Helmsley or Hamlake in the North Riding of Yorkshire. The family also held lands in Holderness, where was situated Ros, to which they gave, or from which they received, their name. Robert succeeded to his father's lands in 1191, paying a relief of one thousand marks. In 1195 he was bailiff and castellan of Bonneville-sur-Touques in Lower Normandy, near which the Norman lands of the family lay." [3]

"The manor [at Roos, Yorkshire] was from the reign of Henry I. the seat and property of the noble family of Roos, one of whose barons had the glory of leading the second division of the English army at the battle of Cressy. The site is still visible of the castle of the former barons; and in part of the old moat have been lately found a misericorde dagger and some amber beads. The place confers the original title on the present family of De Ros." [4]

Roos Spelling Variations

Anglo-Norman names tend to be marked by an enormous number of spelling variations. This is largely due to the fact that Old and Middle English lacked any spelling rules when Norman French was introduced in the 11th century. The languages of the English courts at that time were French and Latin. These various languages mixed quite freely in the evolving social milieu. The final element of this mix is that medieval scribes spelled words according to their sounds rather than any definite rules, so a name was often spelled in as many different ways as the number of documents it appeared in. The name was spelled Ros, Roose, Ross, Ruse and others.

The Roos 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: Spem successus alit
Motto Translation: Success nourishes hope
