People Wikidata records as born in a place inside Castleblayney’s urban area (the CSO’s 2022 urban area), a hospital or district within it included, whose English Wikipedia article agrees. People who only lived here, adult performers and people known mainly for crimes aren’t listed.
Their Wikidata birthplace may be a county or just “Ireland”, a townland or village we don’t list, another town, or missing, or their article may give no birthplace. We only list people both 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 English Wikipedia (each person’s article confirms the birthplace; linked, not quoted). A birthplace is placed in a town by its own Wikidata item, its Logainm place name, or a point inside its CSO 2022 outline; a birth recorded only as one of the five cities stays on the city’s page. Ranked by the number of articles. Fields are read from Wikidata’s description and occupations. “The usual town”: everyone listed across Irish towns.
