Origin
Meaning and origin of Soucy
The surname Soucy originated in France, specifically in the region of Normandy. It is believed to have derived from the Old French word "sous," meaning "under," and the word "cité," meaning "city," suggesting that the name referred to someone who lived near or under the walls of a fortified town or city.
The earliest known record of the Soucy name dates back to the 12th century in Normandy. It is mentioned in several historical documents from that time period, such as the Cartulaire de l'abbaye de Préaux, which contains references to individuals with the surname Soucy.
One of the earliest notable individuals with the Soucy surname was Raoul de Soucy, a Norman knight who participated in the Third Crusade under King Richard I of England in the late 12th century. Another early figure was Guillaume de Soucy, a nobleman and landowner in Normandy in the 13th century.
In the 14th century, the Soucy name appeared in the Cartulaire de l'abbaye de Saint-Wandrille, a collection of charters and records related to the abbey of Saint-Wandrille in Normandy. This document mentions several individuals with the surname Soucy who were involved in land transactions and other matters related to the abbey.
During the 16th century, the Soucy family established itself in the region of Poitou in western France. One notable member of the family from this period was Jacques de Soucy, a distinguished military commander who served in the Wars of Religion in France during the late 16th century.
Another prominent figure with the Soucy surname was Jean-Baptiste Soucy, a French architect and engineer who lived in the 17th century. He was responsible for the design and construction of several notable buildings in Paris, including the Collège des Quatre-Nations (now known as the Institut de France).
In the 18th century, the Soucy name was found in various regions of France, including Normandy, Poitou, and the Paris area. One notable individual from this period was Pierre-François Soucy, a French explorer and navigator who participated in several voyages to the Pacific Ocean and the Northwest Coast of America in the late 18th century.

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

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Soucy (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
