People whose Wikidata birthplace is Méry-sur-Oise itself, matched by its INSEE code (a commune merged into it counts when the dates allow), whose French Wikipedia article agrees, and their English article too when they have one. A hospital or neighbourhood recorded without its commune isn’t matched. People who only lived here, adult performers and people known mainly for crimes aren’t listed.
Their Wikidata birthplace may be a hospital, a neighbourhood or a wider area, another commune, or missing, or their articles may not name a birthplace. We only list people the sources agree on; editing Wikidata or Wikipedia changes this page at the next refresh.
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. Fields are read from Wikidata’s description and occupations. “The usual town”: everyone listed across French towns.
