Meaning
a medieval Castilian name, possibly from Latin nonus, 'ninth', or nunnus, 'grandfather'
The story
Nuño and Portuguese Nuno share a medieval Iberian lineage whose meaning remains uncertain: possibly Latin nonus, "ninth," or nunnus, "grandfather." Their related spellings also hold different histories. In Castilian legend, Nuño Rasura serves as a judge alongside Laín Calvo; his statue still stands on Burgos’s Arco de Santa María, a real monument to a legendary figure. The Portuguese Nuno Álvares Pereira belonged to the world of documented battles. He commanded the army at Aljubarrota in 1385, then took a strikingly different path: giving away his wealth and entering the Carmelite convent he had founded. There he served as a lay brother and organized food for the poor. The medieval name thus reaches us through a carved civic legend in Spain and, in its Portuguese form, the life of a commander who eventually exchanged military authority for service within a religious community.

Births registered in South Australia (not all of Australia) by first name and year of registration, 1944–2017, from the state’s Births, Deaths and Marriages registry, which publishes every name down to a single birth in capitals; a spelling its export repeats inside a year is counted once, and from 2018 only a top 100 is published, so the series ends at 2017.

Not on the record in Puerto Rico, Ireland, New Zealand, Scotland and Poland: those registries withhold small counts, so rare uses may sit below their floors.
Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown. Not on the Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years. Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
