The western seacoast of Scotland and the rugged Hebrides islands made up the ancient Kingdom of Dalriada, the ancestral home of the Glassock family. Glassock is a name for a person with gray hair. The surname Glass is derived from the Gaelic word glas, which means gray, however, it may also be a shortened Anglicized form of the surname MacGille Glais, which means son of the gray lad. 1

In England, the name is an occupational name for "one who made or sold glassware." 2

In 1506 there is record of a grant of half the lands of Langilculcreich in Bute to Alexander Glass. The name is also in record in Perth in 1674, and fifteen of the name are recorded in the Commissariot Record of Dunblane from the sixteenth to the eighteenth century." 4

United States Glassock migration to the United States +

Numerous Scottish settlers settled along the east coast of the colonies that would become the United States and Canada. Others traveled to the open country of the west. At the time of the American War of Independence, some remained in the United States, while those who remained loyal to the crown went north to Canada as United Empire Loyalists. The highland games and Clan societies that sprang up across North America in the 20th century have helped many Scots to recover parts of their lost traditions. Research into passenger and immigration lists has revealed some of the very first Glassocks to arrive in North America:

The Glassock 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: Luctor
Motto Translation: I struggle, but am not overwhelmed.
