In an attempt to escape the chaos experienced in England, many English families boarded overcrowded and diseased ships sailing for the shores of North America and other British colonies. Those families hardy enough, and lucky enough, to make the passage intact were rewarded with land and a social environment less prone to religious and political persecution. Many of these families became important contributors to the young colonies in which they settled. Early immigration and passenger lists have documented some of the first Onsloes to arrive on North American shores:

The Onsloe 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: Festina lente
Motto Translation: Be quick without impetuosity.
