"Orys slew Argilac and took Argilac's castle, kingdom, daughter, sigil and house words. House Baratheon became the Lord of the Stormlands."

Orys Baratheon Profile

Orys Baratheon, the original holder of the title.

Lord Paramount of the Stormlands is a title held by the ruler of the Stormlands from their seat at Storm's End. Former holder Robert Baratheon passed the title to his younger brother, Renly Baratheon, after taking the Iron Throne. Before Robert, the title was held by his father Steffon Baratheon. It has been held by a member of House Baratheon since the War of Conquest.

After Robert and Renly deaths, the title should fall to Stannis Baratheon, middle brother of Robert and Renly, as the only surviving Baratheon brother. However, with the outbreak of the War of the Five Kings, Stannis declared himself king, as he was the rightful heir. Stannis fought against Robert's alleged sons - Joffrey, and then Tommen - who are actually bastards of incest between Queen Cersei and her twin brother Jaime. Both Stannis and Joffrey (and later Tommen) were left fighting over claim to the throne and rule of House Baratheon itself, and thus the title of Lord Paramount of the Stormlands is also in dispute.

With the deaths of Stannis Baratheon and Tommen, the only legitimate connection to the Baratheon bloodline would be Jon Snow (Aegon Targaryen) or Daenerys Targaryen since the Targaryens are distant blood relations with the Baratheons: the founder of House Baratheon, Orys Baratheon, was the half brother of Aegon The Conquerer.
