Aerea's twin sister was Rhaella not Rhalla, and Aeryn Targaryen doesnt exist, he was replaced with daenerys targaryen, oldest daughter of Jaehaerys I... other than that, incredible
The quiz is based off the books not the show. As Jon has not been revealed as a Targaryen (and may not be because of how poorly the show handled that) I can't put him in here.
*There a few half Targaryen missing: Valena Velaryon (whose mother was a Targ), Aemma Arryn (daughter of Daella Targaryen), Laena and Laenor Velaryon (children of Rhaenys Targaryen).
*You include all the named children of Daemon Blackfyre except one: Aenys Blackfyre.
*Alysanne ("Alyssane") and Rhaelle ("Rhalla") are mispelled.
Maelys "The Monstrous" Blackfyre is missing. Also if you're including Rhaenyra's Velaryion children, then you should include Ser Laenor Velaryion and Laena Velaryion, because their mother was a Targaryen.
Orys Baratheon's birth year is wrong. He was Aegon the Conqueros's brother and best friend, he fought in Aegon's Conquest and he was Aegon's first Hand, so I highly doubt he was born a year after Aegon's death.
*You include all the named children of Daemon Blackfyre except one: Aenys Blackfyre.
*Alysanne ("Alyssane") and Rhaelle ("Rhalla") are mispelled.
It's good queen AlySaNNe Targaryen though, not Alyssane Targaryen
He died in 37 AC btw.
