Families began migrating abroad in enormous numbers because of the political and religious discontent in England. Often faced with persecution and starvation in England, the possibilities of the New World attracted many English people.

Some of the first immigrants to cross the Atlantic and come to North America bore the name Cosbye, or a variant listed above: John Cosby who settled in Virginia in 1654; Hannah Cosby settled in Charles Town in 1763; William Cosbey arrived in Philadelphia in 1874.

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: Sub libertate quietem
