The history of the last name Kersaint

The surname KERSAINT originated in the Brittany region of northwestern France during the medieval era. It is believed to be derived from the Breton words "ker" meaning "home" or "village" and "sant" meaning "saint," suggesting that the name may have referred to someone who lived near a particular saint's chapel or church.

One of the earliest recorded instances of the KERSAINT name can be found in the Cartulaire de Redon, a medieval cartulary or collection of charters from the Abbey of Redon in Brittany, dating back to the 9th century. The name appears in various spellings, such as "Kersainct" and "Kersainct-Gily," indicating its evolution over time.

In the 13th century, a notable figure named Olivier de Kersaint was mentioned in the records of the Duchy of Brittany. He was a knight and seigneur (lord) of the Kersaint estate, which was located in the parish of Plougasnou, near the city of Morlaix.

The KERSAINT name gained further prominence in the 16th century with Guy de Kersaint (1508-1572), a Breton nobleman and military leader who fought in the Italian Wars and the French Wars of Religion. He was known for his bravery and loyalty to the French crown.

Another significant figure was René de Kersaint (1615-1683), a Breton lawyer and writer who served as a magistrate in the Parlement of Brittany. He authored several legal treatises and was recognized for his expertise in Breton customary law.

In the 18th century, Armand Guy Simon de Kersaint (1742-1793) was a French naval officer and revolutionary. He served in the French Navy and later became a member of the National Convention during the French Revolution. He was executed during the Reign of Terror for his moderate political views.

The KERSAINT surname has also been associated with various places in Brittany, such as the communes of Kersaint-Plabennec and Kersaint-Landunvez, which likely derived their names from the original KERSAINT family or estate.
