Ogot was born Grace Emily Akinyi to a Christian family on 15 May 1930 in Asembo, in the district of Nyanza, Kenya – a village highly populated by the predominantly Christian Luo ethnic group. Her father, Joseph Nyanduga, was one of the first men in the village of Asembo to obtain a Western education. He converted early on to the Anglican Church, and taught at the Church Missionary Society’s Ng'iya Girls’ School. From her father, she learned the stories of the Old Testament and it was from her grandmother that Ogot learned the traditional folk tales of the area from which she would later draw inspiration.
