Octávia
Octávia is a given name, primarily female, of Latin origin. It derives from the Roman family name Octavius, which itself is a derivative of the Latin word "octavus," meaning "eighth." The name suggests a connection to being the eighth child or born on the eighth day. While traditionally masculine in Roman times, Octavia became a popular feminine form.
Historically, notable figures named Octavia include Octavia the Younger, the sister of the Roman Emperor Augustus.
