I would have thought your unsung heros should have been the natives, who chose not to butcher the various settlers as they stepped off thier boats. In all honesty that sacrifice is what lead to the possibility of a colony, let alone the formulation of a nation under the pretext layed down by the gentlemen the OP mentions. And make no mistake, a sacrifice it most assuredly was. The native culture that existed in America before the settlement of the continent by Europeans, barely exists at all now, but for in some very isolated areas, and in nothing like the same state in which it was found.
Thank them for your current position, thank them for your constitution. Without thier staggering forebearance, America would never have even become a
glimmer in the eye of its founders.
