The Parwars have twelve _gotras_ or main sections, and each _gotra_
has, or is supposed to have, twelve _muls_ or subsections. A Parwar
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.
