All who defend liberty from the grasping hands of her enemies can be called
True Sons and Daughters of Liberty!
"Liberty cannot be preserved without a general knowledge among the people, who have... a right, an indisputable, unalienable, indefeasible, divine right to that most dreaded and envied kind of knowledge, I mean the characters and conduct of their rulers."
John Adams
Original flag of the Sons of Liberty
This flag was sometimes called “The Rebellious Stripes Flag.” If on thinks it looks something similar to the current United States flag, that's not without reason. The colors were not always uniform, however. Sometimes colors like yellow, blue, or green were used. There is speculation, but is is unknown exactly why there are nine stripes.
Second “Rebellious Stripes Flag”
This is the later Sons of Liberty flag. It is even more obviously the ancestor of the current flag of the United States. Each stripe definitely represents one of the thirteen colonies. Colors were still not always uniform, but red and white was common.
The liberty tree and the liberty tree flag
The Original Liberty Tree was an Elm in Boston. It was the tree from which the Sons of Liberty hung their effigies of tax collectors and later had many demonstrations. Many chapters of the Sons of Liberty would used different types of trees. From the trees they would place various massages and decorations. When there was to be a meeting, they would place a flag on a pole sticking up above the tree. Many early liberty trees were cut down by the British, though in one instance a British soldier was killed when a liberty tree being cut down fell on him. This flag itself was not used by the early Sons of Liberty, but came into use sometime closer to the Revolution. It was flown from a liberty pole at the battle of Concord.
