A French surname that likely began as a place-name or neighborhood name, with some forms linked to old words for a rocky or gravelly shore.

Etymology
The available historical note groups Ardoin with forms such as Ardohain and Ardoln and suggests an old place-name origin. It also points toward a French word-family connected with a shore, bank, or stony riverside area, so the surname likely began as a name for someone from a particular locality or neighborhood. Because the excerpt is brief and somewhat noisy, the exact root is not fully secure.
History
Ardoin is a French surname found especially in French-speaking and Francophone-descended communities. In North America it is often encountered in Cajun and Louisiana French contexts, where older French family names were preserved after migration. Variant spellings and record-by-record variation are common, which is consistent with the multiple forms hinted at in the source excerpt.
