Tosia

Tosia is a Polish feminine diminutive form, derived as a pet form of Antonina or Antonia, which trace back to the Latin family name Antonius, of uncertain ancient origin though possibly Etruscan. The name entered widespread use through the veneration of Saint Anthony of Padua and other saints bearing the Antonius lineage. Related forms include Tonia, Tonya, Antonia, and the masculine Antoni.
