Origin of the term "Upstate"

[Chris Wholers]

This may be one of those questions that doesn't have an answer, but I'm
trying to figure out if there's any documented origin for the term "upstate"
(and "downstate" as well).  Does anyone have any idea where these terms were
first used?  Or any hints as to where to look?


Thanks,

Chris
