Iroquois Genealogy Society. Our mission is to encourage interest in the genealogy of the Hodinöhsö:ni' (Iroquois) Nations– Seneca, Cayuga, Onondaga, Oneida, Mohawk, Tuscarora and associated peoples.
The Clerk's Office of the Seneca Nation of Indians welcomes genealogy inquiries. However, because such research is very time consuming, we feel it is reasonable to charge a fee of $50.00 for this service. It is free for enrolled Senecas.
