Meaning & origin(measured from records)
1. literally ‘the French’ or ‘the Frenchman’, probably a regional name for someone who came from the lie de France. In the Middle Ages the French king held sway over a smaller territory than present-day France, and its boundaries tended to vary, but the lie de France was always at its center. 2. from the personal name Frangois, Latin Franciscus (see Francis).

About this data
measured from records inferred from the name graph machine-generated
These figures come from the data snapshot of and will change as it is rebuilt.
Statistics are aggregated from the Mondonomo name corpus; related names and etymology are inferred from the name graph; pronunciation and any machine-marked transliterations are model-generated. Read how the numbers are made, including their known failure modes, and where the data comes from.
Reference works we consult — surname dictionaries, official name registers, Wikidata and Wiktionary — are named directly, beside the claims they support. The per-country source counts also include datasets of person records: we publish how many there are and their authority tier, but not their names.
