United States Onslow migration to the United States +

At this time, the shores of the New World beckoned many English families that felt that the social climate in England was oppressive and lacked opportunity for change. Thousands left England at great expense in ships that were overcrowded and full of disease. A great portion of these settlers never survived the journey and even a greater number arrived sick, starving, and without a penny. The survivors, however, were often greeted with greater opportunity than they could have experienced back home. These English settlers made significant contributions to those colonies that would eventually become the United States and Canada. An examination of early immigration records and passenger ship lists revealed that people bearing the name Onslow arrived in North America very early:

The Onslow 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.
