Show ContentsSemor History, Family Crest & Coats of Arms

When the ancestors of the Semor family emigrated to England following the Norman Conquest in 1066 they brought their family name with them. They 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 Semor family

The surname Semor 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

Semor Spelling Variations

The English language only became standardized in the last few centuries. For that reason, spelling variations are common among many Anglo-Norman names. The shape of the English language was frequently changed with the introduction of elements of Norman French, Latin, and other European languages; even the spelling of literate people's names were subsequently modified. Semor has been recorded under many different variations, including St. Maur, Seymour, Seymer, Seymar, Seamor, Seamour, Seemour and many more.

Migration of the Semor family

To escape the uncertainty of the political and religious uncertainty found in England, many English families boarded ships at great expense to sail for the colonies held by Britain. The passages were expensive, though, and the boats were unsafe, overcrowded, and ridden with disease. Those who were hardy and lucky enough to make the passage intact were rewarded with land, opportunity, and social environment less prone to religious and political persecution. Many of these families went on to be important contributors to the young nations of Canada and the United States where they settled. Semors were some of the first of the immigrants to arrive in North America: William Seymour who settled in Virginia in 1653; George Seymour settled in Barbados in 1679; William Seymour settled in Maryland in 1725; John Seymer was banished to Barbados in 1685.



The Semor 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.
