Titus Tatius
Tatiana is a female name of Sabine and Latin origin, a feminine derivative of the Sabine-Latin name Tatius. Titus Tatius was the name of a legendary king of the Sabines, an Italic tribe living near Rome around the 8th century BC. Because the Romans absorbed the Sabines, the name Tatius remained in use in the Roman world and during the first centuries of Christianity, as well as its diminutive Tatianus and the feminine Tatiana.
