The name Tuliana is a girl's name of Latin origin. Tuliana and discussed in our forums with posts like "Quick Question Thread?!".
From the experts:
The unusual hybrid Tuliana, which rhymes with Juliana, combines the Roman offshoot Tulia with the more familiar Ana, the Latinate form of Anna or Ann. Tulia comes from the Roman family name Tullius, best known as the middle name of the philosopher Cicero. While Tuliana is intriguing, any little Tuliana, upon introducing herself, will always be asked, "Juliana?"
