Tathiana / Tatiana / Tatyana

Tathiana is a variant of Tatiana, a name of Roman origin, derived from the Roman family name Tatius. The name Tatius is believed to be of Sabine origin, an ancient Italic tribe. The most famous bearer of the name was Titus Tatius, a legendary king of the Sabines who ruled alongside Romulus.

The name Tatiana gained popularity in Russia due to Saint Tatiana of Rome, an early Christian martyr. It became a very common name in Russia and other Slavic countries, often associated with royalty and nobility. The 'Th' spelling in Tathiana is less common and might be a creative or regional variation.
