What are the Igbo traditions regarding funerals?

This is only a part of the answer! One of the Traditions is that the Children of the bereaved would have to travel on the below basis to inform of the death -

1. If it is a mother, to her father's home;

2. If it is a father, to his mother's home of birth.

Another is that the corpse is usually placed in the hole with the feet facing the direction of the ROAD, and never the Head.
