It seems to me, if I recall correctly, that Jane McCrea was engaged to an officer named Jones, not Campbell.  I haven't checked to be sure.  But I think Jones was a British officer with Burgoyne, and he had local Loyalist connections, I think.  Also, wasn't Jane from New Jersey (?) and wasn't she staying with a friend at Fort Edward, a widow Campbell?  The whole story deserves more research.  The McCrea killing captured the attention of the Americans, but a far worse, much more horrible atrocity occurred almost at the same time in present Washington County.  This was the murder of the entire Allen family, including an infant child.  And this is almost entirely forgotten.
