Etymology
This name comes from French la mothe / la motte, meaning a mound, hill, or earthwork. In surname use, it usually pointed to someone who lived near such a feature or came from a place named for it. The underlying sense is topographic: a natural rise of ground, or an artificial mound associated with a castle or fortification.
History
LaMothe and related spellings are found in French and French-derived naming traditions, especially where place-names based on motte-type earthworks were common. The name was later carried into North America by French settlers and their descendants, so it is most often encountered today in French-Canadian, Acadian, and broader Francophone families. English-language records often flatten the spacing and capitalization, producing forms like Lamothe or LaMothe.
