Figure 69: Patrilateral Cross Cousin Marriage

Members of four different lineages intermarry.
No cousin rule is applied.

The patrilateral cross cousin marriage rule is applied:
A man marries his father's sister's daughter, his patrilateral cross cousin. The marriage rule in this case effects a different pattern of exchanges in comparison with the previous generation; while women of the first tier marry men from one group (A to B, B to C , etc), women of the next marry in the reverse direction (A to D, B to A, etc.)

The application of the patrilateral rule in the third generation reverses the circulation of women again, thus reiterating the pattern of the initial generation.
