Show ContentsOnsley History, Family Crest & Coats of Arms

The present generation of the Onsley family is only the most recent to bear a name that dates back to the ancient Anglo-Saxon culture of Britain. Their name comes from having lived in the settlement of Onslow in the county of Shropshire. The surname Onsley 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 Onsley family

The surname Onsley was first found in Shropshire at Onslow, where the family went "as far back as the time of Richard I., and probably much earlier. The first recorded ancestor is John de Ondeslowe, whose grandson, Waring, was father of 'Roger de Ondelsowe, juxta Shresbury,' whose son Thomas was living in the twelve [year] of Edward II, 1318." 1

The Onsley 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.
