Hmm -- got this off Wikipedia -- "The Iroquois lived in extended families divided clans headed by clan mothers that grouped into moieities ("halves"). The typical clan consisted of about 50 to 200 people. The division of the Iroquois went as follows: Cayuga Moiety (A) clans: Bear, Beaver, Heron, Turtle, Wolf Moiety (B) clans: Turtle, Bear, Deer Tuscarora Moiety (A) clans: Bear, Wolf Moiety (B) clans: Eel, Snipe, Beaver, Turtle, Deer Seneca Moiety (A) clans: Heron, Beaver, Bear, Wolf, Turtle Moiety (B) clans: Deer, Hawk, Eel, Snipe Onondaga Moiety (A) clans: Tortoise, Wolf, Snipe, Eagle, Beaver Moiety (B) clan: Bear, Hawk, Eel, Deer Oneida Moiety (A) clan: wolf Moiety (B) clans: Bear, Turtle Mohawk Moiety (A) clans: Wolf, Bear Moiety (B) clan: Turtle." Their source was "Tribes of the Iroquois Confederacy" by Michael Johnson. Is that book incorrect?
