Because of Nnachi's continued concern, his father Eberechi accompanied him to seek guidance from the oracle. According to oral tradition, the goddess Ngwu revealed that she had been neglected and forgotten.
The goddess demanded that a female cow be dedicated to her shrine, which was located close to Nnachi's home, as an act of atonement. In obedience, Eberechi and Nnachi purchased a female cow and dedicated it to the goddess.
According to the traditional account, shortly afterwards Nnachi's wife became pregnant and gave birth to a male child. The child was named Nwangwo, in honour of the goddess Ngwu. Nwangwo later became the ancestor of Ubahangwo.
The same woman later gave birth to another son named Okwurekwu — meaning “the goddess said it” — who became the ancestor of Okworokwu. Nnachi's second wife, Nwankwo, later gave birth to sons named Umunnadila, who became the ancestor of Umunankwo, and Azuwike, whose Ozo title name was Ezike, who became the ancestor of Umuzike.
