People Wikidata records as born in a place inside Treorchy’s built-up area (the ONS 2022 boundary), 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 bigger area (“London”), 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.
