Civil Registry Documentation

Civil registry records form the primary documentary basis for the biographical claims in this dossier. The records consulted cover birth and marriage registration in Saint-Denis and the arrondissements of Paris relevant to the Willmann and Ferrero families. The marriage record of 22 March 1898 is the most directly relevant: it establishes the identities of both parties, confirms Felix Ferrero’s occupation, and places Blanche Denise within the professional social environment in which Rembrandt Bugatti was also active. A birth-date discrepancy remains unresolved: two dates appear in available sources. Resolution requires direct access to the original Saint-Denis civil register entry. Until confirmed, all dossier materials use circa 1880 for the birth date.
