Bastards may sometimes use the arms of their father's house with an added distinction. The arms of a house belong to that family, as in Germany and Italy, and may be used by all trueborn descendants of that house.
Most of the Seven Kingdoms use escutcheon-shaped coats of arms, but Dornish houses favor circular coats of arms that are not widely seen anywhere else. While real-world heraldry makes extensive use of words and jargon specific to blazonry, Westerosi arms are mostly described in standard English. In this regard, Westeros resembles early medieval or Dark Age societies, before the rules of heraldry were properly developed and widely accepted. Heraldry in the Seven Kingdoms serves largely the same purpose as in medieval Europe, but Westerosi heraldry is significantly less formalized. Heraldry in Westeros and in the real world

Their older brother Rhaegar was already dead by the time Dany was born, and she was one of the last two Targaryens seemingly left. As the youngest daughter of Aerys and Rhaella, she was behind her older brother, Viserys. When the show began, Dany, as she is known to her real fans, was second in line to the thrown in the Targaryen line. The parts that are important to Westeros in there are the “House Targaryen,” “Queen of The Andels and the First Men,” “Protector of the Realm,” and “Regent of the Seven Kingdoms.”
Game Of Thrones fans are of course very familiar with Daenerys Targaryen, played wonderfully by Emilia Clarke, whose full title is so easy for everyone to remember: Daenerys of the House Targaryen, the First of Her Name, The Unburnt, Queen of the Andals, the Rhoynar and the First Men, Queen of Meereen, Khaleesi of the Great Grass Sea, Protector of the Realm, Lady Regent of the Seven Kingdoms, Breaker of Chains and Mother of Dragons.
