Tavia

Tavia is a short form of Octavia, a Roman gens (family name) meaning 'eighth'. The name Octavia was traditionally given to the eighth-born child, or to a child born into the gens Octavia. While Octavia has a long history, Tavia as a standalone name is a more modern development, emerging as a diminutive that gained independent usage.

Its usage as a given name is less common than its longer form, Octavia, but it carries the same classical elegance and numerical significance. Tavia often appeals to those looking for a less formal or more unique alternative to Octavia, while still retaining a connection to its Roman roots.
