If you meant 'who is Leia', then i can answer your question. Leia was Princess of Alderaan, adoptive daughter of Bail Organa. but she was really one of the two Skywalker kids. Her parents were Anakin Skywalker (later Darth Vader), and Senator/former Queen of Naboo Padme Amidala (later Padme Amidala Skywalker, but that was not known in between Eps 2 and 3). Luke Skywalker was Leia's older brother, and Leia went on to become a Jedi Knight, Senator, President of the New Republic, and Chief of State when Mon Mothma was President of the New Republic. Leia married Han Solo, had three kids, Jaina, Jacen, and Anakin. Anakin died in the Yuzahan Vong wars, and Jacen turned to the Dark Side and became Darth Cadeus. Jaina and Luke went on to kill Darth Cadeus, and Jaina was the only survining Solo child. Leia's full title, gathered from the info from all the Star Wars books and movies is:
Jedi Knight Leia Organa Skywalker Solo, Former Princess of Alderaan, former Chief of State for the New Republic, President of the New Republic, and Former Senator of Alderaan.
Please note: this title may not be accurate, as it is my gathering of some of Leia's former titles. If you find any inaccuracies, feel free to edit them.
If you weren't talking about Leia, then I can't help you.
