Ned and Robert believe she was slain by Rhaegar Targaryen, who would have been the next king had Robert not taken the throne (Robert actually mentioned this in the episode last night, at least that it was Rhaegar who killed her).
They were not married. And I have some theories about what happened to Lyanna Stark and why, but I can't go into them in this thread...
