675 people counted by Census Bureau — Surname Frequency 2010, 2010. Exact figures are national registers' own counts, while figures marked ≈ and est. are Mondonomo’s estimates, counted from our sources and calibrated against those registers; hover one for how far to trust it in that country. A dash means neither exists.

Registers cited: Census Bureau — Surname Frequency 2010; Census Bureau — Surname Frequency 2020; INSEE — Fichier des noms de famille (1891–2000); INE — Padrón per-token widgets (current living counts, given + apellidos); Familienaam.be — Belgian family-name frequency (population register). Figures without a register are Mondonomo estimates; see Methodology.

Other names spelled this way(inferred from the name graph)

Filion is also recorded as another name, grouped separately because the records behind them do not connect to the one described above.

Grouping is the name graph's, not a register's: two spellings join a group when the evidence links them, so a group is a claim about the records rather than about the people.

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.
