Well think of something like (I know this is going to make you cringe anon) Benedict Arnold. He switched sides to serve his own interests and was thwarted in the end. There could be other Colonial or British defectors who might be hunted by Connor.

Plus I think ultimately Connor has a thing against the British because they said the Brits destroyed his village as a child (during the French and Indian War).

And fyi Washington was never confirmed to be a Templar; all that was shown in the AC2 glyphs is that he held an apple (which may explain how he was able to shape a new nation).
