The history of the last name DeMars

The surname DEMARS is of French origin and dates back to the medieval period. It is believed to have originated in the Normandy region of northern France, where it was initially derived from the old French words "de" meaning "from" and "Mars," which was a reference to the Roman god of war.

One of the earliest known references to the DEMARS name can be found in the Domesday Book of 1086, which was a comprehensive record of landowners and property commissioned by William the Conqueror after the Norman conquest of England. The name appears in various spellings, such as "de Mars" and "de Marres," indicating that it was already in use among Norman families during this time.

In the 13th century, records show that a family bearing the DEMARS name held lands and properties in the village of Marres, located in the Calvados department of Normandy. This area is likely the place of origin for the surname, and it is possible that the name was initially derived from this location.

One of the earliest recorded individuals with the DEMARS surname was Raoul de Mars, a Norman knight who participated in the Third Crusade (1189-1192) under the leadership of Richard the Lionheart. Another notable figure was Jean de Mars (c. 1320-1389), a French nobleman and military commander who served under King John II during the Hundred Years' War.

During the Middle Ages and Renaissance, the DEMARS name also appeared in various forms across different regions of France. For instance, in the Picardy region, the name was often spelled as "Demarre" or "Demarres," while in the Ile-de-France region, it was commonly written as "Demars" or "Desmars."

In later centuries, several notable individuals carried the DEMARS surname. These include Jacques Demars (1570-1638), a French playwright and poet who lived during the reign of Louis XIII, and Pierre Demars (1677-1756), a French architect who designed several churches and public buildings in Paris.

Another prominent figure was Michel-René Demars (1782-1837), a French general who served under Napoleon Bonaparte and fought in numerous campaigns, including the Napoleonic Wars. He was recognized for his bravery and leadership on the battlefield and was awarded the prestigious Légion d'honneur.
