Show ContentsThornby History, Family Crest & Coats of Arms

The name Thornby is of Anglo-Saxon origin and came from when a family lived in Thornborough found in the counties of Buckinghamshire and North Yorkshire. Thornby is a topographic surname, which was given to a person who resided near a physical feature such as a hill, stream, church, or type of tree. During the Middle Ages, as society became more complex, individuals needed a way to be distinguishable from others. Toponymic surnames were developed as a result of this need. Various features in the landscape or area were used to distinguish people from one another. In this case the surname was originally derived from the Old English thorn broc which means that the original bearers of the surname Thornby were named due to their close proximity to the stream by the thorns. 1

Early Origins of the Thornby family

The surname Thornby was first found in Cumberland where they held a family seat at Selsheyd (now known as Selside.) This chapelry, in the parish, union, and ward of Kendal is now in the county of Westmorland. "The chapel, dedicated to St. Thomas, was erected in lieu of a more ancient edifice, about 1720, by the inhabitants, on a site given by William Thornburgh, Esq.; and was rebuilt on an enlarged scale in 1837, at an expense of about £600." 2

The first records of the family were found in nearby Yorkshire where Robert de Thorneberg was recorded in the Curia Regis Rolls of 1208 and Hugh de Thornburgh was listed in the Subsidy Rolls of Yorkshire in 1327. 3 Later in Yorkshire, we found Ricardus de Thornbargh recorded in the Yorkshire Poll Tax Rolls of 1379. 4

"The name of Thornber was represented by Thornbur in Gloucestershire in the 13th century. " 5

The Thornby 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: Spectemur agendo
Motto Translation: Let us be judged by our acts
