Glassy History, Family Crest & Coats of Arms
The ancient Dalriadan-Scottish name Glassy is a nickname 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. 
In England, the name is an occupational name for "one who made or sold glassware." 
Early Origins of the Glassy family
The surname Glassy was first found in Buteshire (Gaelic Siorrachd Bhòid), an island region of western Scotland within the ancient Kingdom of Dál Riata, now part of the Council Area of Argyll and Bute. Glass is a "parish, of which the name, in the Gaelic language, signifying "grey," is descriptive of the uncultivated portion of its surface, is about eight miles in extreme length, and five miles in extreme breadth, comprising an area of nearly 19,000 acres." 
Early records of the family are very scarce. The name is thought to be "a shortened form of Mac Gille glais [who were] families locally called barons from the fifteenth century till recently. 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." 
Much father to the south in Devon, England "the present home of the name of Glass in this county is in the Exbourne district. Nicholas Glass was the name of the mayor of Barnstaple in 1787 and 1804. Glass was the name of two Tiverton churchwardens in 1723 and 1724. The name is also established in Wiltshire."

Early Notables of the Glassy family (pre 1700)

Migration of the Glassy family
Significant portions of the populations of both the United States and Canada are still made up of the ancestors of Dalriadan families. Some of those in Canada originally settled the United States, but went north as United Empire Loyalists in the American War of Independence. The late 19th and early 20th centuries saw the ancestors of many Scots on both sides of the border begin to recover their collective national heritage through Clan societies and highland games. Some of the first North American settlers carried this name or one of its variants: Duncan Glass who settled in Virginia in 1651 with his wife Mary; William Glass settled in New England in 1709 with his wife, two sons and two daughters.
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 Translation: I struggle, but am not overwhelmed.
