This presentation details the age validation process undertaken for Mrs. Caterham in accordance with the international standards follwed by non-profit scientific institutes: the Gerontology Research Group (GRG) and the International Database on Longevity (IDL). Primary source documents—including birth registration, marriage certificate, census entries, and continuous identity linkages were critically examined to establish the integrity of her life record chain. Secondary sources such as electoral rolls, local press reports, and family attestations provided supplementary confirmation of identity continuity across more than a century. Particular methodological attention was given to reconciling discrepancies in early census data and ensuring documentary consistency through the UK General Register Office archives.
