The story of Fermin
Saint Fermín is honored as the first bishop of Pamplona, and his feast on the seventh of July is the occasion of the Sanfermines — the week-long festival that includes the encierro, the morning run through the streets ahead of the bulls. Hemingway put it into a novel in 1926 and it became internationally famous. The name is used across Spain and Mexico and reaches American records from both.

The Ardis test
Every popular name lives one long story — a climb, a peak, a slow settling back. Fermin's later chapters haven't been written yet, so we borrowed them: Ardis climbed just as high around 1903, and its whole arc is on record. Line the two peaks up, and Ardis's path sketches the road Fermin is walking now.
