The history of the last name DeBlois

The surname DEBLOIS is of French origin, deriving from the Old French words "de blois" which translate to "from Blois". Blois is a city in the Loire Valley region of central France, dating back to the 9th century. The surname likely originated as a way to identify individuals who hailed from this area.

The earliest known record of the DEBLOIS name appears in the 12th century Cartulary of Notre-Dame de Chartres, a collection of charters and deeds from the cathedral in Chartres, France. In this document, a person named Gervaise de Blois is mentioned, indicating the use of the locational surname.

During the Middle Ages, the DEBLOIS surname was particularly prevalent in the regions surrounding Blois, such as Orléanais and Touraine. It is also found in various medieval records and documents from this time period, including the Livre des Bourgeois de Blois, a register of citizens from the city of Blois.

One notable historical figure with the DEBLOIS surname was Jean de Blois (c. 1275-1335), a French nobleman and military commander who fought in the Hundred Years' War. He participated in several battles against the English and was held captive for a period of time.

Another prominent individual was Étienne de Blois (c. 1096-1154), a French prelate who served as the Archbishop of Canterbury in England from 1123 to 1128. He played a significant role in the conflicts between King Henry I of England and the Church.

In the 17th century, a branch of the DEBLOIS family emigrated from France to Canada, establishing themselves in the colony of New France. One of the earliest recorded DEBLOIS in Canada was Jacques de Blois (1655-1718), who settled in Quebec City and worked as a merchant and landowner.

Guillaume de Blois (1618-1693) was a French Jesuit missionary who spent several years in what is now known as the Great Lakes region of North America, working among various Native American tribes.

As the surname spread across Europe and North America, various spelling variations emerged, such as DeBlois, De Blois, and Deblois.
