Secret Wildlings

[TheSeer27]

Just a thought. As we know occasionally Wildlings get passed the Wall and if they are lucky enough to survive an attack from say The Karstarks or other Northern houses that hunt down Wildlings, isn't possible some have secreted into the Realm without people knowing? So does anyone think any of the characters in AGOT could be Wildlings? Like say Bronn for instance? Not saying he is, but I feel like if this is possible, becoming a sellsword is really the only option they would have since they obviously don't have any lands or houses.
