Origin
Meaning and origin of Dejordy
The surname DEJORDY has its origins in France, with records dating back to the 16th century. It is believed to have derived from the Old French words "de" meaning "of" or "from" and "jordi" or "jorde," which referred to a person's occupation or trade as a gardener or vineyard worker.
The earliest known reference to the name DEJORDY can be found in a parish record from the village of Châteauneuf-du-Pape in the Rhône Valley region of southern France, dated 1587. This document mentions a certain Jean DEJORDY, who was a vineyard worker in the area known for its renowned wines.
In the 17th century, the DEJORDY name appears in various ecclesiastical records and legal documents from the neighboring regions of Provence and Languedoc. One notable mention is in a land registry from the town of Aix-en-Provence, dated 1642, which lists a Pierre DEJORDY as a landowner and cultivator of olive groves.
As the DEJORDY family spread across France in the following centuries, variations in spelling began to emerge. Some historical records from the 18th century show the name written as "DeJordi," "De Jordy," or even "Dejordis."
One of the earliest recorded DEJORDY individuals of note was François DEJORDY (1720-1789), a prominent merchant and vintner from the city of Avignon. His successful wine trade helped establish the family's reputation and wealth in the region.
Another notable figure was Marie-Thérèse DEJORDY (1768-1842), a renowned horticulturist and botanist from Marseille. She is credited with introducing several new plant species to the Mediterranean region and authored several influential works on gardening and agriculture.
In the 19th century, the DEJORDY name gained further recognition with the accomplishments of Auguste DEJORDY (1812-1887), a respected lawyer and judge from Montpellier. He was known for his progressive views on legal reform and his advocacy for the rights of marginalized communities.
The DEJORDY lineage also includes Jean-Baptiste DEJORDY (1844-1912), a celebrated architect from Lyon who designed several iconic buildings and landmarks in the city, including the impressive Palais de la Bourse.
As the DEJORDY family continued to spread across France and eventually to other parts of Europe and beyond, the name has become associated with a rich heritage rooted in agriculture, horticulture, and a deep connection to the land.

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.

Keep in mind that these are self-reported numbers.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
