The du Casse arms were recorded in Guyenne, c. 1663.
Guyenne was the great wine country of south-western France, shipping claret to England for centuries. The trade made merchant families rich, they bought vineyards and estates with the money, and land of that kind brought arms with it.
This is where the arms were entered in the register. Families often moved to other parts of the country, so the same name can turn up in more than one region.
In France, a coat of arms was a mark of honor that passed down through the male line to all legitimate descendants. Families often used the same shield without changes to show their shared heritage. If a branch wanted to stand out, they could add a small mark to their shield to show their specific place in the family tree.
The family name Du Casse originates from the Gascony region of southwestern France, specifically within the historic province of Guyenne. The name is derived from the Gascon dialect word "casse," which refers to an oak tree. This suggests that the earliest ancestors likely lived near a prominent oak or in a wooded area, leading neighbors to identify them by their surroundings. By 1663, records confirm that the family was well-established in the region, where they were deeply integrated into the local social and economic life of the French countryside. As the family grew, members became known for their service in maritime and military roles, which helped spread the name beyond their ancestral roots in Guyenne to other parts of the French empire.
Derived from the Old French verb casser meaning to break.
