Origin
Meaning and origin of Tournoux
The surname Tournoux originated in France during the medieval period, deriving from the Old French word "tournois" which referred to a type of coin minted in Tours. This suggests the name may have denoted someone involved in the minting or trading of this particular currency.
The earliest recorded instances of the name can be traced back to the 13th century in historical records from the Touraine region of central France, where the city of Tours is located. Variations in spelling included Tournois, Tournoix, and Tournoys.
In the 14th century, a notable figure bearing this surname was Jean Tournoux, a wealthy merchant and landowner from the town of Amboise along the Loire River. Records indicate he held significant property and influence in the region during the 1370s.
Another early bearer of the name was Guillaume Tournoux, a cleric who served as the Dean of the Cathedral Chapter in Tours from 1412 to 1437. His name appears in numerous ecclesiastical documents from that era.
During the Renaissance, the Tournoux family produced several renowned scholars and intellectuals. Michel Tournoux (1508-1564) was a celebrated humanist philosopher who taught at the University of Paris and wrote extensively on classical literature.
In the 17th century, Jacques Tournoux (1620-1701) was a respected jurist who served as a judge in the Parlement of Paris, one of the most powerful judicial bodies in France at the time.
The 18th century saw the rise of Etienne Tournoux (1756-1817), a politician who played a prominent role in the early years of the French Revolution as a member of the National Constituent Assembly representing the Touraine region.
While the surname Tournoux has French origins, it eventually spread to other parts of Europe and beyond through migration over the centuries. However, it remains most deeply rooted in its ancestral homeland of central France.

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