Any info/rumors/headcannons about who was on Aegon V's kingsguard? (Spoilers Extended)

On the ASOIAF wiki, the only confirmed member is Dunk. We also don't know who was hand of the king for King Egg. Why all the secrecy? What is George cooking? Egg knighted Barristan but Barristan only got his white cloak once Jaehaerys II was king.
