Thibodeaux
A French surname from a personal name, most famously associated with Louisiana Creole and Acadian families.
The #2,602 most common surname in the United States (2010 Census) — about 1 in every 22,292 Americans shares it.
Etymology
Thibodeaux is a French surname ultimately built on the old given name Thibaut, Theobald, or a regional form of that name. The ending -eaux is a French spelling pattern found in some family names, especially in western France and in surnames carried to French colonial North America. In plain terms, the name means "descendant of Thibaut/Theobald" rather than describing a trade or place.
History
The surname is strongly associated with French-speaking communities in Louisiana, especially Cajun and Creole families with roots in Acadian and French colonial migration. In North America it appears in several spellings, with Thibodeaux becoming the best-known Louisiana form. The name’s presence in southern Louisiana reflects the broader survival of French family names after Acadian displacement and resettlement.
