Most of the catalogue carries no origin at all, and that is deliberate: guessing a name's language from how it looks is exactly the kind of invention this site avoids. The names below are the ones where an origin was actually recorded.
Why the list is short
Because 51 names out of eleven thousand have a recorded origin in English, and the rest are blank rather than guessed. An empty field here means nobody has sourced it, not that the name came from nowhere — the gap is honest and it is the next thing worth filling.
Every count on this site is a tally of real registrations: pet licences and shelter intakes published as open data by New York, Seattle, Austin, Montgomery County, Cambridge, Zurich, Basel and three Australian councils. Popularity here is the average share a name holds across those registers, so a name common in a small city is not buried by one common in a large one. Nine of the eleven sources are North American, so read the ordering as naming in those places rather than worldwide.
