The history of the last name Sansoucy

The surname SANSOUCY originated in France and is a locational name referring to those who came from the village of Sans-Soucy, near the town of Dreux in northern France. The name derives from the French phrase "sans souci" which means "without worry" or "carefree".

In the late 16th century, King Henry IV of France built a palace near Dreux and named it the Château de Sans-Soucy, meaning "the Carefree Castle". This palace likely contributed to the name's popularity in the region. The earliest known record of the SANSOUCY surname dates back to 1598 in the village of Sans-Soucy.

One of the earliest recorded bearers of the SANSOUCY name was Jean SANSOUCY, born in 1635 in the village of Sans-Soucy. He was a farmer and landowner in the region. Another notable early bearer was Marie SANSOUCY, born in 1672, who was a member of the local nobility and owned several estates in the area.

In the late 17th century, some members of the SANSOUCY family emigrated to New France (modern-day Canada) and settled in the provinces of Quebec and Acadia. One of the earliest settlers was Pierre SANSOUCY, born in 1683 in the village of Sans-Soucy, who arrived in Quebec in 1705 and became a successful merchant and landowner.

During the French and Indian War (1754-1763), a soldier named Joseph SANSOUCY, born in 1732 in Quebec, fought for the French forces and was captured by the British. After the war, he remained in Canada and became a farmer in the Beauce region of Quebec.
