What does the name Cadeo mean?

The surname is one of the most ancient names that came from France during the Middle Ages. It is a Breton name for a person who was a person who was small but a strong fighter. The name Cadeo is derived from the Old French word "cad," which means "little fighter."

Early Origins of the Cadeo family

The surname Cadeo was first found in Brittany (French: Bretagne), where they are recorded as an ancient family with lands, manors, and estates.

The family was involved in many of the early conflicts between French royalty and local Lords regarding the jurisdiction of their lands. A family member by the name of Cadeau d'Arcy would later hold large estates in Picardy and in île-de-France. He became secretary to the King of France and was ennobled by the French Parliament as a viscount on 30th June 1830. Many family members later migrated to Acadia in Canada. Some settled in the province of Quebec, while others left for Louisiana in the forced exodus of the Acadians.

Pierre Cadieux, son of Jean and Marie (née Valade), settled in Quebec in the 17th century. He married Marguerite Menard, daughter of Jacques and Catherine (née Fortier), at Boucherville on 11th February 1697. He married for the second time on 29th May 1702 at Pointe-aux-Trembles to Jeanne Mersan. 1

The Cadeo 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: Rien ne me touche
Motto Translation: Springing to life, do not touch
