been thinking about this, the problem with this theory is that John looks nothing like a Targareyan, he's dark haired while they are all blonde and have the purple eyes. Could he be the last of House Reyne of Castamere, they were destroyed by Tywin early in his reign. Did honourable Ned promise a dying princess of House Reyne that he would protect her baby, would explain why he had to keep his identity secret.

Robb Reyne was a famous knight and partisan of
Daemon Blackfyre.
The lord of House Reyne during the rule of Lord
Tytos Lannister was dubbed the "
Red Lion of Castamere". When the match of
Genna Lannister and
Emmon Frey was announced, the Red Lion angrily left the hall at
Casterly Rock. Later during the rule of Tytos, Lord Reyne
rebelled against his overlord along with the
Tarbecks of
Tarbeck Hall. Lord Reyne was an experienced warrior while Lord Tytos was rather weak, so it appeared that their rebellion could be successful. In the end Tytos's young son and heir,
Tywin Lannister, held the command of the Lannister army. Tywin besieged the castles and destroyed the rebels. After the rebellion the seats of the rebels were brought down and both houses were exterminated. It is not known if the rebels died in acts of war or that they were executed.
