which boasted of common descent (from a common sire) and was united into a separate community by certain social and religious institutions, but the origin and nature of which nevertheless remained obscure to all our historians.
Elsewhere, in speaking of the Punaluan family, we saw how the gens was constituted in its original form. It consisted of all individuals who by means of the Punaluan marriage and in conformity with the conceptions necessarily arising in it made up the recognized offspring of a certain ancestral mother, the founder of that gens. Since fatherhood is uncertain in this form of the family, female lineage is alone valid. And as brothers must not marry their sisters, but only women of foreign descent, the children bred from these foreign women do not belong to the gens, according to maternal law. Hence only the offspring of the daughters of every generation remain in the same sex organization. The descendants of the sons are transferred to the gentes of the new mothers. What becomes of this group of kinship when it constitutes itself a separate group, distinct from similar groups in the same tribe?
As the classical form of this original gens Morgan selects that of the Iroquois, more especially that of the Seneca tribe. This tribe has eight gentes named after animals: 1. Wolf. 2. Bear. 3. Turtle. 4. Beaver. 5. Deer. 6. Snipe. 7. Heron. 8. Hawk. Every gens observes the following customs:

The son never followed his father in the office of sachem, because the Iroquois observed maternal law, in consequence of which the son belonged to another gens. But the brother or the son of a sister was often elected as a successor. Men and women
