Cousin, nephew, it doesn't matter. Given the Targaryen propensity towards incestual relationships, it's very possible that Jon is Dany's nephew, cousin, uncle, brother, and grandfather all rolled into one.
Seriously, at this point the Targaryen family tree probably looks like a wreath made of Gordian Knots. I'm surprised there aren't a tribe of Hillbilly Targaryens who talk about how people have "purty mouths."
