Origin
Meaning and origin of Beuoy
The surname BEUOY originated in the Brittany region of northwestern France during the late Middle Ages. It is derived from the Old French words "beu" meaning "deep" and "ouey" meaning "water", likely referring to someone who lived near a deep body of water or stream.
One of the earliest recorded instances of the name BEUOY can be found in a 13th century cartulary, a medieval manuscript collection of charters and deeds, from the Abbey of Saint-Mathieu in Finistère, Brittany. The name is spelled "de Beuoye" in this document, referring to a landowner or tenant in the area.
In the 14th century, a variant spelling "Bevoye" appears in the Rolls of the Parlement of Paris, which were records of court proceedings during that time. This suggests that the name had spread to the capital region by the 1300s.
A notable figure with the surname BEUOY was Jean Beuoy, a merchant and alderman in the city of Rennes, Brittany, who lived from approximately 1420 to 1488. He was involved in the local government and trade affairs of the city.
Another early bearer of the name was Marguerite Beuoy, born around 1510 in the village of Plouguerneau, Finistère. She is mentioned in parish records as having married a local fisherman named Yves Keravel in 1535.
In the 17th century, the name BEUOY appears in the records of the Huguenot church in Caen, Normandy, suggesting that members of the family had moved to that region and were part of the Protestant minority in France at that time.
A prominent individual with this surname was Jacques Beuoy, a French naval officer and explorer who lived from 1650 to 1725. He is known for his expeditions to the Caribbean and his role in the colonization efforts of the French West Indies.

The bar chart below shows how Beuoy bearers described their own race and ethnicity on the 2020 Census form. 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. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Beuoy surname at the time of the 2020 Census, not any inherent property of the name itself.
