After attending for many years Diop conferences in USA, Dr Assoumou explains how the origins of someone are important for anybody. He begins by telling why he was interested in social sciences even if he is a surgeon. He focuses on his village, and it can be the same examples in many other villages in Africa. He did a research, and found some reasons why people go from one village to another. The organization of the family is explained according to Ntoumou people. Some customs are still applied by people, namely polygamy, the marriage of widow, beliefs, the names of the children. Finally the genealogy of the village is given in a simple way.
