Meaning and origin of Antonia
Antonia is often said to mean “uncertain; feminine of Antonius”; the origin is uncertain, though it is usually linked to Latin and Italian roots.
Antonia is the feminine form of Antonius, the name of an old Roman family whose origin is unknown; the popular meaning priceless is a later interpretation. Antonia Minor, the daughter of Mark Antony, was the mother of the emperor Claudius. The name appears in literature too, most notably in Willa Cather's novel My Ántonia. Antonia has been used across Europe for centuries and feels elegant, classic and warm. Toni, Tonya and Nia are nicknames, and it pairs well with short middle names.
