Origin
Meaning and origin of Delehoy
The surname DELEHOY has its origins in France, with the earliest records of the name dating back to the 12th century. It is believed to have derived from the Old French words "de le hoi," which translates to "of the hill" or "from the hill." This suggests that the name likely originated from a specific geographic location or a place name associated with a hill or elevated terrain.
During the Middle Ages, many surnames were derived from the locations or places where families resided, and DELEHOY appears to follow this pattern. The name may have been adopted by an individual or family who lived near or owned property on a hill or elevated area.
One of the earliest recorded instances of the name can be found in the Cartulaire de l'abbaye de Marmoutier, a medieval manuscript from the 12th century, which mentions a person named Robertus de le Hoi. This document provides valuable insight into the early usage and spelling variations of the name.
In the 14th century, the name appeared in various documents and records across France, including the Registers of the Parlement of Paris, where a Guillaume Delehoy was mentioned in 1387. This particular spelling variation, with the elements "de" and "le" combined, became more common over time.
Notable individuals bearing the surname DELEHOY include:
1. Jean Delehoy (1532-1597), a French composer and music theorist known for his contributions to the development of Renaissance polyphonic music.
2. Étienne Delehoy (1642-1715), a French architect who designed several notable buildings in Paris, including the Hôtel de Lauzun.
3. Marie-Thérèse Delehoy (1754-1828), a French painter and miniaturist who gained recognition for her portraits and religious works.
4. Charles Delehoy (1819-1892), a French lawyer and politician who served as a member of the National Assembly during the Second Republic.
5. Émile Delehoy (1878-1949), a French poet and writer known for his works celebrating the beauty of nature and rural life in Normandy.
While the surname DELEHOY is not among the most common in France today, its rich history and origins can be traced back several centuries, reflecting the diverse cultural and geographic influences that have shaped French surnames over time.

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 Delehoy surname at the time of the 2020 Census, not any inherent property of the name itself.
