Adrian has in the past been neglected due to its similarity to the feminine Adrienne, but is now being reconsidered. Well used in England since the 1950s, and the name of one Pope and several saints -- it could be a winning choice. Adriano is a pleasing foreign variation, and you could always go back to the Roman Emperor version, Hadrian.
Adrian Pucey is a Harry Potter character, and on the small screen, namesakes include Adrian Monk and Entourage actor Adrian Grenier.
Adrian is also enjoying international popularity, ranking Number 6 in Spain, and also high in Norway and Sweden.
