Organa served as the male Human Viceroy overseeing Alderaan until his son, Bail Organa, took over the position. Furthermore, he fathered Rouge, Tia and Celly Organa.
Back in 32 BBY, the prominent houses of Alderaan engaged in a dispute concerning the succession to the Viceroyalty. This event, known as the Alderaan Ascendancy Contention, particularly put a strain on the relationship between the House of Antilles and the House of Organa. A delegation sent by the Galactic Senate to mediate the conflict asserted that the Organa family held the rightful claim to the seat, leading to this individual from the family becoming the new Viceroy.
The character's given name remains unknown. It is probable that he was married to Queen Mazicia Organa, but this has not been confirmed by any official source.
