The caste have exogamous sections, which are of the usual low-caste
type, with titular or totemistic names. Those of the Chhattisgarhi
Rawats are generally named after animals. A curious name among the
Mahakul Ahirs is Mathankata, or one who bit his mother's nipples. The
marriage of persons belonging to the same section and of first cousins
is prohibited. A man may marry his wife's younger sister while his
wife is living, but not her elder sister. The practice of exchanging
girls between families is permissible.
