Question: is aegon a real name?
Answer: Aegon is, in some ways, a fitting name for Jon. The first Targaryen king, the man who created the Iron Throne, was also named Aegon, as was Maester Aemon's brother, Aegon the Unlikely, aka Egg. ... Remember, Jon's a true-born heir because Rhaegar annulled his earlier marriage to Elia Martell.
