From Wikidata (CC0: birthplaces, descriptions, years, occupations, how many Wikipedia and sister-site articles cover each person) and French and English Wikipedia (each person’s articles confirm the birthplace; linked, not quoted). Birthplaces are matched to the commune by INSEE code and its history of mergers (INSEE COG 2026). Ranked by the number of articles.
