The ancestors of the Caslake surname lived among the ancient Anglo-Saxon culture. The name comes from when they lived near a stream in which a substantial quantity of the edible plant cress or watercress grew. The surname Caslake is derived from the Old English words cærse, which means cress, and lacu, which means stream. 1 The surname Caslake belongs to the class of topographic surnames, which were given to people who resided near physical features such as hills, streams, churches, or types of trees.

Early Origins of the Caslake family

The surname Caslake was first found in Devon at Kerslake, a hamlet near Tiverton. "Burgesses of that town bore this name in the reign of James I., and Abraham Kerslake was a Tiverton churchwarden in the time of Charles II." 2

The "C" and "K" prefix for the name has always been interchangeable, as the first record of the family was actually found in Somerset. The Assize Rolls of Somerset in 1279 listed Ranulph de Carselak. 3

Migration of the Caslake family

A great wave of immigration to the New World was the result of the enormous political and religious disarray that struck England at that time. Families left for the New World in extremely large numbers. The long journey was the end of many immigrants and many more arrived sick and starving. Still, those who made it were rewarded with an opportunity far greater than they had known at home in England. These emigrant families went on to make significant contributions to these emerging colonies in which they settled. Some of the first North American settlers carried this name or one of its variants: John Kerslake, who sailed to Barbados in 1684. Thomas Carslake journeyed to Boston in 1716 and John Kerslake sailed to Philadelphia in 1868.

The Caslake 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: Ad finem fidelis
Motto Translation: Faithful to the end.
