Origin
Meaning and origin of Derepentigny
The surname DEREPENTIGNY originated in France, with records dating back to the 12th century. It is believed to be derived from the Old French words "de" (meaning "from") and "Repentigny," a place name referring to a small town or village in the Île-de-France region. The name likely indicates that the earliest bearers of this surname hailed from this particular location.
One of the earliest recorded examples of the DEREPENTIGNY name can be found in the Cartulaire de Notre-Dame de Paris, a medieval manuscript compiled in the late 12th century, which mentions a certain "Robertus de Repentigny" as a landowner in the Île-de-France region. This suggests that the DEREPENTIGNY family had already established themselves as minor nobility or landowners by this time.
In the 13th century, a knight named Hugues DEREPENTIGNY is mentioned in several chronicles as having participated in the Seventh Crusade led by King Louis IX of France. His name appears in the roll of knights who accompanied the king to the Holy Land in 1248-1254.
During the 14th century, the DEREPENTIGNY name spread beyond the Île-de-France region, with records indicating bearers of the name in various parts of northern France. A notable figure from this period was Jean DEREPENTIGNY (c. 1320-1385), a wealthy merchant and landowner from Rouen.
In the 15th century, the DEREPENTIGNY family produced several notable figures, including Jacques DEREPENTIGNY (c. 1410-1482), a prominent lawyer and judge who served as the Lieutenant General of the Bailiwick of Rouen. Another member of the family, Guillaume DEREPENTIGNY (c. 1450-1525), was a renowned architect and master builder who worked on several significant religious and secular structures in Normandy.
The 16th century saw the DEREPENTIGNY name spread further across France and into other parts of Europe. One notable bearer of the name during this period was François DEREPENTIGNY (c. 1530-1601), a French explorer and cartographer who accompanied Jacques Cartier on his voyages to the New World and helped map the St. Lawrence River and the eastern coast of Canada.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers.
