You might interested in some of the answers I've provided in the past that shed some insight into the Iroquois (more appropriately known as the Haudenosaunee) Confederacy:

• My humanities teacher claims that in prehistory, human society was generally matriarchal, being ruled by priestesses, and that the main religion was mother-earth worship. She claims that this information is being passively covered up by acedemia. Would you consider this accurate?

• Native Americans in what is now the USA have often been portrayed as having "idyllic" lives before Western colonizers arrived - is there any truth to this? How much "easier" were their daily lives? Before Western diseases and colonists arrived, was it a life of easy hunting and simple living?

• Was sovereignty a part of Native American political thought?

Two of the three links are not specifically about the Haudenosaunee, but include mentions of them and include relevant reference to what you're asking.
