Francisco Coronado? Don Juan de Onate? Pope'? Don Diego de Vargas? George Washington, Don Juan de Anza? Cuerno Verde? Manuelito? Sitting Bull? Satanta?
I would venture a guess that this all depends on who you were when whatever you considered your country crystalized in your mind. Navajos in the 1870's did not consider any American, Mexican or whatever, a founding father. And who do Navajos consider their "founding father's" today? I do not know any Navajos, but I bet not many would call George Washington a "founding father".
The reason I give this example is because I feel the same way. I have a hard time relating to a conversation when someone mentions "founding fathers". And I know several Native Americans and they all feel this way. I have never had one Native American claim George Washington.
