Show ContentsSeamor History, Family Crest & Coats of Arms

Seamor is a name whose history on English soil dates back to the wave of migration that followed the Norman Conquest of England of 1066. The Seamor family lived in Monmouthshire. Their name, however, is a reference to St. Maur, near Avranches, Normandy. 1

"The baronial family of St. Maur, founded by the warrior of Hastings, became extinct in the chief male line at the decease in 1499 of Richard, 6th Lord St. Maur, whose only daughter and heiress, Alice, wedded William, 6th Lord Zouche of Haryngworth. The Seymours, Dukes of Somerset, whose historic greatness needs little of ancestral aid to augment its glory, claim to be a scion of the baronial house, and their pretensions may be sustained by the valuable authority of Camden." 2

Early Origins of the Seamor family

The surname Seamor was first found in Monmouthshire. However, records differ on who was the progenitor of the family. One reference claims that Wido de St. Maur came to England in 1066 but was deceased before 1086 and would have therefore not appeared in the Domesday Book. His son William Fits-Wido held a barony in Somerset, Wiltshire and Gloucester and ten manors in Somerset. 3

"A Gilbertine priory, in honour of the Blessed Virgin Mary, was founded [in Poulton, Gloucestershire] about 1347, by Sir Thomas de Sancto Mauro, or Seymor." 4

Another reference claims they were descended from Roger Sancto Maure who lived during the reign of Henry I and was Lord of Seymour Castle. 5

Seamor Spelling Variations

A multitude of spelling variations characterize Norman surnames. Many variations occurred because Old and Middle English lacked any definite spelling rules. The introduction of Norman French to England also had a pronounced effect, as did the court languages of Latin and French. Therefore, one person was often referred to by several different spellings in a single lifetime. The various spellings include St. Maur, Seymour, Seymer, Seymar, Seamor, Seamour, Seemour and many more.

United States Seamor migration to the United States +

Many English families left England, to avoid the chaos of their homeland and migrated to the many British colonies abroad. Although the conditions on the ships were extremely cramped, and some travelers arrived diseased, starving, and destitute, once in the colonies, many of the families prospered and made valuable contributions to the cultures of what would become the United States and Canada. Research into the origins of individual families in North America has revealed records of the immigration of a number of people bearing the name Seamor or a variant listed above:

Seamor Settlers in United States in the 17th Century
  • Richard Seamor, who arrived in Hartford, Connecticut in 1639 7
Seamor Settlers in United States in the 18th Century
  • John Seamor, who landed in Virginia in 1703 7
  • Jane Seamor, who arrived in Virginia in 1711 7


The Seamor 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: Foy pour devoir
Motto Translation: Faith for duty.
