Glassey History, Family Crest & Coats of Arms
The ancient Dalriadan-Scottish name Glassey 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 Glassey family
The surname Glassey 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."

Glassey Spelling Variations
In the Middle Ages, the translation between Gaelic and English was not a highly developed process. Spelling was not yet standardized, and so, an enormous number of spelling variations appear in records of early Scottish names. Glassey has appeared as Glass, Glas, MacGilleglas, Glasse and others.
Early Notables of the Glassey family (pre 1700)
Notable amongst the Clan from early times was John Glas (1695-1773), Scottish sectary, only son of Alexander Glas (d. 1724), minister of Auchtermuchty, Fifeshire, afterwards of Kinclaven, Perthshire. He was born at Auchtermuchty on 21 Sept. 1695.

Migration of the Glassey family to Ireland
Some of the Glassey family moved to Ireland, but this topic is not covered in this excerpt.
The descendants of the Dalriadan families who made the great crossing of the Atlantic still dot communities along the east coast of the United States and Canada. In the American War of Independence, many of the settlers traveled north to Canada as United Empire Loyalists. Clan societies and highland games have allowed Canadian and American families of Scottish descent to recover much of their lost heritage. Investigation of the origins of family names on the North American continent has revealed that early immigrants bearing the name Glassey or a variant listed above include:

Emigration to New Zealand followed in the footsteps of the European explorers, such as Captain Cook (1769-70): first came sealers, whalers, missionaries, and traders. By 1838, the British New Zealand Company had begun buying land from the Maori tribes, and selling it to settlers, and, after the Treaty of Waitangi in 1840, many British families set out on the arduous six month journey from Britain to Aotearoa to start a new life. Early immigrants include:

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.
