Origin
Meaning and origin of Ambron
The surname AMBRON is of French origin, with its roots tracing back to the medieval period. It is believed to have derived from the Old French word "ambrón," which referred to a type of wild plum tree. This suggests that the name may have initially been given as a descriptive nickname to someone who lived near or was associated with such trees.
The earliest recorded mention of the AMBRON name can be found in the 13th-century cartulary of the Abbey of Saint-Germain-des-Prés in Paris, where a certain Gervais Ambron is listed as a tenant in the year 1247. This indicates that the name was already in use by that time in the region around Paris.
In the 14th century, the AMBRON name appears in various documents from the Champagne region of northeastern France. For instance, a Guillaume Ambron is mentioned in the tax records of the town of Troyes in 1369. This suggests that the name had spread to other areas of France by that point.
One of the earliest notable individuals with the AMBRON surname was Jean Ambron, a French cleric and theologian who lived in the late 15th century. He was born around 1450 in the town of Ambronay, which may have derived its name from the same root as the surname.
During the 16th century, the AMBRON name gained prominence in the region of Normandy. A notable figure from this period was Nicolas Ambron, a merchant and landowner from the town of Caen, who was born in 1522 and died in 1598.
In the 17th century, the AMBRON name can be found in various records from the Provence region in the south of France. One noteworthy individual was Pierre Ambron, a lawyer and magistrate from Aix-en-Provence, who lived from 1625 to 1689.
As the AMBRON surname spread across France over the centuries, it also found its way to other parts of Europe and beyond. For example, in the 18th century, a Dutch merchant named Pieter Ambron established a trading company in the Dutch East Indies (present-day Indonesia).
While the AMBRON name may have originated as a descriptive nickname related to a particular type of tree, it has since become a well-established surname with a rich history spanning several centuries and various regions of France, as well as other parts of the world.

The bar chart below shows how Ambron 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 Ambron surname at the time of the 2020 Census, not any inherent property of the name itself.

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