I like the layout of this timeline. Revolutionary War Timeline – Events of The American Revolution. My biggest complaint is it neglects the critical Battle of Saratoga, which is the reason the French signed the alliance in the first place.
Sons of Liberty - Well, those in Boston anyway. There were similar organizations scattered throughout the Thirteen Colonies in the years leading up to the American Revolutionary War, and, yes, "Sons of Liberty" was a common name ;
Rogers Rangers possibly the most famous of the Ranger units. Its notoriety being created firstly by Rogers' own writings(he was not ashamed to put himself in the lime light) and more recently by the film Northwest Passage in 1940 starring Spencer Tracey.
