But the most rigorous obligation for the members of the same clan is that of not marrying in it. To take a wife having the same _totem_ is considered as a most culpable act; it is a crime sometimes punished by death.[894] The Iroquois law regulating marriages recalls, in a certain degree, that which takes place among the Kamilaroi of Australia. Thus an Iroquois of the Seneca tribe and of the Wolf clan must not marry a woman belonging, not only to his own clan, but to all the clans of the same name in the five other tribes of the Iroquois. On the other hand, he is perfectly free to marry in any of the seven other clans of his own Seneca tribe.[895] In short, an Iroquois may be endogamous in the tribe, but he must be exogamous from the point of view of the clan or clans. The motive of the prohibition of marriage within the clan is always the supposed relationship. Thus the law of the Tinneh Indians forbids a man of the Chitsang clan to marry a woman of the same clan because that woman is his sister.[896] The children always belong to the _gens_, or clan, of their mother. These rules vary more or less from tribe to tribe, except the prohibition of marriage within the clan, which is strict and general. Thus, among the Omahas, a man may take a wife in another tribe, even if this woman belongs to a clan of the same name as his own; but he cannot marry within his own clan, because all the women of this clan are reputed to be his relations--sisters, aunts, nieces, daughters, etc. We shall see presently to what women these various appellations, which among the Redskins have a much wider sense than with us, are applied.[897] These customs, or very analogous ones, were in force with a great number of American tribes. At the present day the Indians of the Moqui Pueblos still live in their common habitations, as at the time of the conquest, and they are divided into nine clans.[898]
