Show ContentsSlim History, Family Crest & Coats of Arms

The distinguished surname Slim emerged among the industrious people of Flanders, which was an important trading partner and political ally of Britain during the Middle Ages. As a result of the frequent commercial intercourse between the Flemish and English nations, many Flemish migrants settled in Britain. In early times, people were known by only a single name. However, as the population grew and people traveled further afield, it became increasingly necessary to assume an additional name to differentiate between bearers of the same personal name. The manner in which hereditary surnames arose is interesting. Local surnames are derived from where the original bearer lived, was born, or held land. Flemish surnames of this type frequently are prefixed by de la or de le, which mean of the or from the. The Slim family originally lived in some place which experts suggest was named Slanie or Slaney. The surname Slim belongs to the category of habitation names, which are derived from pre-existing names for towns, villages, parishes, or farmsteads, or other places.

Early Origins of the Slim family

The surname Slim was first found in Shropshire where they held a family seat from early times. Rodolphe de Slanie or Slane accompanied the Empress Maude into England about the year 1110.

Over in Ireland, Philip of Slade (died 1326), was Bishop of Cork, born at Slane in Meath. "He became a Dominican friar, and on 20 Feb. 1321 was papally provided to the bishopric of Cork, receiving the temporalities on 17 July following. " 1

Slim Spelling Variations

Flemish surnames are characterized by a large number of spelling variations. One reason for this is that medieval English lacked definite spelling rules. The spellings of surnames were also influenced by the official court languages, which were French and Latin. Names were rarely spelled consistently in medieval times. Scribes and church officials recorded names as they sounded, rather than adhering to specific spelling rules, and people often had their names registered in several different forms throughout their lives. One of the greatest reasons for change is the linguistic uniqueness of the Flemish settlers in England, who spoke a language closely related to Dutch. The pronunciation and spelling of Flemish names were often altered to suit the tastes of English-speaking people. In many cases, the first, final, or middle syllables of surnames were eliminated. The name has been spelled Slaney, Slanie, Slane, Slayney and others.

The Slim 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: Deo duce comite industria
Motto Translation: God is my guide, industry my companion.
