Marriage, Endogamy, Exogamy
It is said that each of the sub-tribes mentioned above was in early times strictly endogamous; for though members of all these subdivisions might freely eat and drink together, intermarriage between them was absolutely forbidden. But all such restrictions on marriage seem to have passed away long since, so that the whole subject has nowadays little more than an antiquarian interest.
No formal hypergamy is recognised, though Kacháris occasionally take wives from the cognate tribes known as Rábhas (Totlás), Koches (Madáhis), and Saraniyas, &c. But such alliances are as a rule not looked upon with favour, and the bridegroom in such cases has generally to make his peace with his fellow-villagers by providing them with a feast in which rice-beer (Zu) and pork are certain to take a prominent place. Children born of such mixed marriages become in all cases members of the father’s subdivision of the Bodo race.
There is little or nothing specially distinctive in the laws of consanguinity or affinity in their bearing on the marriage relationship. A widower may marry his deceased wife’s younger sister, but not the elder, whom he is taught to regard conventionally in the light of a mother. Much the same principle holds good in the case of the re-marriage of widows, which is freely permitted, the one limitation being that a widow may marry her deceased husband’s younger brother, but not the elder.
