Aslet History, Family Crest & Coats of Arms
The origins of the Aslet name lie with England's ancient Anglo-Saxon culture. It comes from when the family lived in one of a variety of similarly-named places. The parishes of Cold Hesleton (Hesleden) and Monk Hesleton (Hesleden) are in Durham. Both date back to Saxon times when they were collectively known as Heseldene c. 1050 and literally meant "valley where hazels grow." 
Haslingden in Lancashire dates back to 1241 when it was known as Heselingedon and meant "valley where hazels grow."  Hazeldon Farm is in Wiltshire, and Hazelton is in Gloucestershire. The surname Aslet belongs to the large category of Anglo-Saxon habitation names, which are derived from pre-existing names for towns, villages, parishes, or farmsteads.
Early Origins of the Aslet family
The surname Aslet was first found in Sussex at ancient manor in or near Dallington.  The name is derived from the Old English words hoesel + denu, which mean "Hazel" + "valley."  Hazleton Abbey was an abbey in Gloucestershire.

Migration of the Aslet family to Ireland
Some of the Aslet family moved to Ireland, but this topic is not covered in this excerpt.
Migration of the Aslet family
To escape oppression and starvation at that time, many English families left for the "open frontiers" of the New World with all its perceived opportunities. In droves people migrated to the many British colonies, those in North America in particular, paying high rates for passages in cramped, unsafe ships. Although many of the settlers did not make the long passage alive, those who did see the shores of North America perceived great opportunities before them. Many of the families that came from England went on to make essential contributions to the emerging nations of Canada and the United States. Research into various historical records revealed some of first members of the Aslet family emigrate to North America: William Hassleton, who came to Barbados in 1679; William Hazledine settled in New England in 1775; Charles Hazeltine settled in Philadelphia in 1774; John Hazelton settled in New York State in 1811.
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: Pro aris et focis
Motto Translation: For our altars and our homes
