There are two predominant stories about the number of children the Oya goddess gave birth to. In one of the stories, it was said that she only had one set of twins. In most stories, she was said to have had nine stillbirths (four Twins and Egungun). She often wore a garment of nine colors to honor her dead children. The number of children she had earned her the nickname – Ọya-Ìyáńsàn-án.
