The Mastin arms were recorded in Poitou, c. 1663.
Poitou was western French farming country, divided among a large number of small landed families. Its gentry were numerous and modest, and even a small estate was enough to justify a shield.
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 Mastin traces its roots back to the historic region of Poitou in western France. By the year 1663, records confirm that members of the family were well established within this area. The name is often linked to the Old French word mastin, which historically referred to a type of sturdy dog or a mastiff. In medieval times, such names were frequently given as nicknames to describe a person who possessed a loyal, watchful, or bold personality. As the family grew, they became part of the local social fabric of Poitou, living through a period of significant religious and political change in seventeenth-century France. Over time, the name traveled beyond these regional borders, eventually spreading to other parts of the world as family members migrated and sought new opportunities.
A Latinized form derived from the Germanic name Masto or Mastoald.
