Origin
The surname "AMPY" is thought to have originated in France during the medieval period. It is believed to be a variation of the Old French word "ampier," which means "to thrive" or "to prosper." This suggests that the name may have been given to someone who was particularly successful or prosperous in their endeavors.
One of the earliest recorded instances of the name "AMPY" can be found in the Records of the Taille of 1292 in Normandy, where a certain Jehan Ampy is mentioned. This document was a tax roll that recorded the names of landowners and their property holdings in the region.
In the 14th century, the name appears in various French records, such as the Cartulary of the Abbey of Saint-Corneille in Compiegne, where a Perrinet Ampy is mentioned in 1376. This suggests that the name was well-established in northern France by this time.
During the 15th century, the name "AMPY" began to spread to other parts of Europe. In 1487, a Flemish merchant named Pieter Ampy is recorded in the archives of the city of Bruges, indicating that the name had made its way to the Low Countries.
One notable figure with the surname "AMPY" was Jean-Baptiste Ampy, a French architect who lived from 1640 to 1712. He was responsible for the design of several churches and buildings in Paris and its surrounding regions, including the Church of Saint-Séverin and the Château de Vaux-le-Vicomte.
Another individual of note was Marie-Louise Ampy, a French educator who lived from 1768 to 1832. She founded one of the first schools for girls in Paris and was a pioneer in the field of women's education during the Enlightenment period.
In the 19th century, the name "AMPY" continued to appear in various records across Europe. For example, a German immigrant named Heinrich Ampy is listed in the passenger records of a ship arriving in New York in 1852, indicating that the name had spread to other parts of the world by this time.
Other notable individuals with the surname "AMPY" include Émile Ampy, a French painter who lived from 1830 to 1890, and Pierre Ampy, a Belgian politician and economist who served as the mayor of Liège from 1891 to 1904.
Overall, the surname "AMPY" has a rich history that spans several centuries and multiple countries, with its origins likely rooted in medieval France. Despite its relatively low frequency, the name has been associated with various individuals who have made significant contributions in fields such as architecture, education, art, and politics.
Demographics
Among Census respondents with the surname Ampy, the largest self-reported group is Black at 95.8%. The next largest groups are Asian/Pacific Islander (1.7%) and Two or More Races (1.7%).
The bar chart below shows how Ampy 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 Ampy surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
