In ACOK Big Walder is talking with Little Walder about the Frey line of succession.
(Bran I, ACoK)
Who is Aegon?
I know in line after Petyr was Aegon Frey (Jinglebell), but he doesn’t have any children. The only other Aegon Frey is Aegon Bloodborn, son of Aenys, also childless. So is this just an error on Martin’s part or am I missing something?
