3. Exogamy.
The Parwārs have twelve gotras or main sections, and each gotra has, or is supposed to have, twelve muls or subsections. A Parwār must not marry in his own gotra nor in the mul of his mother, or any of his grandmothers or greatgrandmothers. This practically bars marriage within seven degrees of relationship. But a man’s sister and daughter may be married in the same family, and even to two brothers, and a man can marry two sisters.
