Follower of Christ or fairy queen
Tiyanna is a modern American elaboration likely derived from Tiana. It blends the roots of Tatiana, a Roman family name associated with a 3rd-century saint, and Christiana, meaning a follower of Christ. In some contexts, it is also linked to the Slavic word for 'fairy queen'.
