The Roos surname, of Norman ancestry, was a name given to a person with red hair which was in turn derived from the Old French nickname le rous, meaning redhead. Another equally valid derivation suggests that the name is a shortened form of the Norman given name Rufus. 1 2 3

Early Origins of the Roos family

The surname Roos was first found in Devon. The first on record was Radulphus le Rufus, a knight in the train of William the Conqueror who became one of the Justices Itinerant of the counties of Wiltshire, Dorset, Somerset, Devon and Cornwall temp. Henry II. It is from this eminent person that the family of Edmerston and Halton, co. Devon descend. 4

"Rouse or Rowse is the name of an ancient Cornish family of Halton. Antony Rouse or Rowse, of Halton, was High Sheriff in the reign of Elizabeth. " 5

"The manor of Helston, which was always considered as belonging to the dutchy, was alienated during the usurpation of Cromwell, when it was sold to Anthony Rowse; but on the restoration of the Stuarts, it returned again into its original channel. This manor was sold in the year 1798, under the Land-tax redemption act, to John Rogers, Esq. of Penrose, who is the present proprietor." 6

Some of the family were also found at early time further north at Mearly in Lancashire. "The chief part of the township was granted by Jordan le Rous to Stephen, afterwards called de Merley, whose daughter married Adam de Nowell, and carried the Hall and manor into that family, 38th of Edward III." 7

And still farther north, Rousay and Eagleshay is a parish, in the North Isles of the county of Orkney, Scotland. 8

By the time of the Hundredorum Rolls of 1273, the popularity of the name was evident. That rolls included: Alexander le Rous, Cambridgeshire; Juliana la Rouse, Oxfordshire; Alicia Rouze, Cambridgeshire; John le Rus, Lincolnshire; Gilbert Russ, Lincolnshire; and Lucia la Russe, Oxfordshire. 9

Once more into the archives we delved to find the Assize Rolls for Lancashire listing Wilekin Rous in 1225; John Russe in Wiltshire in 1218; Symon le Rus in the Feet of Fines for Huntingdonshire in 1253; and Margareta le Ruse in Staffordshire in 1285. 10

Roos Spelling Variations

Endless spelling variations are a prevailing characteristic of Norman surnames. Old and Middle English lacked any definite spelling rules, and the introduction of Norman French added an unfamiliar ingredient to the English linguistic stew. French and Latin, the languages of the court, also influenced spellings. Finally, Medieval scribes generally spelled words according to how they sounded, so one person was often referred to by different spellings in different documents. The name has been spelled Rous, Rouse, Rowse and others.

To escape the political and religious persecution within England at the time, many English families left for the various British colonies abroad. The voyage was extremely difficult, though, and the cramped, dank ships caused many to arrive in the New World diseased and starving. But for those who made it, the trip was most often worth it. Many of the families who arrived went on to make valuable contributions to the emerging nations of Canada and the United States.

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: Vescitur Christo
Motto Translation: He feeds on Christ.
