Origin
The surname Tanguy originated in Brittany, a cultural region in the northwest of France. It likely arose in the medieval period, deriving from the Breton personal name Tangi, which itself comes from the old Celtic word "tanau" meaning "fire" or "brightness." The earliest recorded spelling of the name appears to be Tanguy.
In the 12th century, the name is found in the Cartulaire de l'abbaye de Landevenec, a medieval manuscript containing records of the Landevenec Abbey in Finistère, Brittany. An entry from 1162 mentions a certain "Radulfus Tangui." This suggests the name was already well-established in the region by that time.
The Tanguy surname later spread beyond Brittany, with instances recorded in various regions of France. In the 14th century, the Livre des bourgeois de Rouen, a record of the citizens of Rouen, includes a "Guillaume Tanguy" listed in 1352.
Notable individuals with the surname Tanguy include Tanguy du Chastel (c.1475-c.1540), a French knight and military commander who served under King Francis I. He fought in several campaigns, including the Battle of Marignano in 1515.
Yves Tanguy (1900-1955) was a renowned French surrealist painter, known for his distinctive dreamlike landscapes. Born in Paris, his works were influenced by the surrealist movement and the writings of André Breton.
Marcel Tanguy (1892-1972) was a French art dealer and gallerist who played a significant role in promoting surrealism and modern art. His gallery, Galerie Tanguy, hosted exhibitions by artists such as Salvador Dalí and René Magritte.
Tanguy Ndombele (born 1996) is a professional football player from France who currently plays as a midfielder for Tottenham Hotspur in the Premier League. He has also represented the French national team.

Demographics

The bar chart below shows how Tanguy 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 Tanguy 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.

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.
