***SPOILER ALERT***BIG TIME***
As far as Jon Snow is concerned, his mother was almost certainly NOT a targaryan. That said, there is some extremely compelling evidence that his father was Rhaegar Targaryan.
This has been discussed in extreme depth on other forums, but it seems clear to me that Jon Snow is the son of Lyanna Stark and Rhaegar Targaryan.
Hm, i'd love to hear the evidence of this if you've got the time.
It starts with Ned Stark. He is haunted by Lyanna's words, "Promise me Ned."
At first, it seems like it is in reference to him taking her body home to Winterfell. If that were so, I don't think those words would haunt him like they do through book 1.
Let's look at Robert's rebellion.
Near the end, Rhaegar is dead, King's Landing has been taken, the siege on Storm's End has been lifted. The war is over. Ned and his 6 buddies ride to Dorne, to the Tower of Joy, to rescue Lyanna. She is being guarded by three members of the kingsguard. Ser Gerold Hightower, the lord commander, Ser Arthur Dayne, the consensus best knight in the seven kingdoms, and Ser Oswell Whent.
Why would three members of the kingsguard, and arguably, the two most important, be at the tower of joy with Lyanna Stark? They are charged with keeping the king of the realm safe. Here is where we run into a series of ifs.
#1 If Rhaegar and Lyanna were married, any children of theirs would be legitimate heirs to the throne. This would require Rhaegar to be married to two women at the same time. There is precedent for this in the past. Aegon the Conqueror was married to two women at the same time(both his sisters...)
Robert always claimed that Rhaegar kidnapped Lyanna and raped her. This is unlikely, given what we know of Rhaegar. From Barristan Selmy, we learn that Rhaegar was a gentle soul who didn't appear to have any cruelty in him. This is backed up by Jon Connington, but seeing as Connington was in love with Rhaegar, his testimony is somewhat biased. Selmy, though, has no reason to be anything but truthful about who Rhaegar was, and he has nothing but great things to say about him. That hardly paints the picture of a rapist.
It seems more likely that Rhaegar fell in love with Lyanna when they met at Harrenhal. Rhaegar won the tourney there and named Lyanna the queen of love and beauty, despite his own wife being present. Anyway, it seems like there was some romance brewing there.
#2 If Lyanna was pregnant with Rhaegar's son, that son would be the heir to the throne of Westeros.
At this point, Rhaegar's son, Aegon, had been murdered(or so the world thought). This means his next son would have a stronger claim than Viserys or Daenerys, Rhaegar's siblings.
Ned finds Lyanna daying in "a bed of blood" after he and Howland Reed narrowly survive battle with the knights of the kingsguard.
This is where Lyanna says, "Promise me Ned." It seems more likely that this promise that has haunted him is of much higher importance.
Imagine how Robert would react if he brought home Lyanna's baby...a legitimate son of Rhaegar Targaryan who Robert hates. Do you think that child would be safe? We've seen how crazy Robert gets when it comes to Targaryans.
Perhaps the promise is to do whatever it takes to save her child. He sacrificed his own honor to honor his sister's dying wish.
Anyway, there is a lot more evidence out there, but I have detailed the most compelling evidence.
