This indicates that, currently, the surname has a very limited presence and is concentrated in a single country, which may be a significant clue as to its origin. The concentration in France suggests that the surname probably has French roots or, alternatively, that its expansion has been mainly within French territory. The history of the region and the linguistic characteristics of the surname allow us to infer that its origin could be linked to the nobility tradition or French toponymy, given that many surnames with a similar structure derive from places or castles in France.
The exclusive presence in France may also reflect a surname of relatively ancient origin, which was not widely dispersed by mass migrations or colonization, but remained in a specific region.

The structure of the surname, which combines elements that evoke a castle or fortress, also supports this hypothesis. In short, the current distribution and the regional historical context allow us to assume that Chastellux has a French origin, possibly linked to some locality or fortification that served as a reference for the formation of the surname.
Etymology and Meaning of Chastellux
