Show ContentsMersereau History, Family Crest & Coats of Arms

The prestigious French surname Mersereau is a proud sign of a rich and dynamic ancestry. The earliest forms of hereditary surnames in Artois were the patronymic surnames, which are derived from the father's given name, and metronymic surnames, which are derived from the mother's given name. The patronyms were derived from a variety of given names that were of many different origins. As well as the names of the saints of the Christian Church, many of the most common French are derived from personal names of Germanic origin. They derive from the language of the Franks who controlled most of France after the fall of the Holy Roman Empire. The surname Mersereau is derived from the name Marchand, which is derived from the Latin and Old French words for merchant.

Early Origins of the Mersereau family

The surname Mersereau was first found in Artois, a former province of northern France.

Active in the events of the times, the family branched and held extensive lands in Paris, Berry, and Lorraine where they intermarried with many notable and important families. From there as ambassadors, diplomats and statesmen they founded branches in Geneva, Italy and Germany.

Amongst the many titles and lands they were awarded for their contributions to the King were de Beauepas, du Collenu, de L'Ecluse, de Maisoncelle, de Richemont, du Mas, de Malaval and de Touville, several of which were for their lands and estates in both Normandy and Bretagne.
