The nine of thirteen is correct from what I recall: New Hampshire was the ninth to ratify on 21 June 1788, making the Constitution the law of the land. The remaining were Virginia (ratified just four days after NH), New York (26 July 1788), North Carolina (significantly later: 21 November 1789), and Rhode Island (29 May 1790, after receiving assurances of a forthcoming Bill of Rights): save for VA and NC, nothing contiguous there.
Given that eleven of thirteen were in the fold by mid-1788, non-ratification doesn't seem likely.
