The story
Antonia is the ancient feminine of Antonius, the name of one of Rome's great families, the gens Antonia. Its deepest root is a genuine mystery: the family name is thought to be Etruscan, from a language that died without leaving a dictionary, so the honest answer is that its original meaning is lost. The popular gloss priceless is a later, affectionate invention rather than a true translation, and we would rather tell you that than pretend. What is not lost is the lineage the name carries. Antonia Minor, daughter of Mark Antony, was mother to one Roman emperor and grandmother to another; Willa Cather made My Antonia one of the great American novels. Stately and warm at once, an-TOH-nee-a, it is a steady classic across the United States and the whole Spanish-speaking world. Timeless and dignified, Antonia hands a child a Roman house, a place in literature, and a name that has never needed a fashion.
