From the experts:
Spelled this way, Briana was coined by Edmund Spenser for his great literary work, The Faerie Queene, which gives the now-overexposed name a far classier pedigree than it's usually credited with. But spelling variations Breana, Breanna and onward are popular too, though feel more invented -- probably because they are. One enduring appeal of Briana and sisters is that they're girl names that mean strong, brave, or powerful, which may be why George R. R. Martin names his warrior maiden Brienne of Tarth.
