Hello Chief Naja Chinyere Njoku. It's great to see your Researching to See If there is a Genetic Connection between the Osu people in Ghana 🇬🇠and the Osu people of Eastern Part of Nigeria 🇳🇬 ?
OSU OF NIGERIA is not the same as OSU OF GHANA
The Osu of Ghana and the Osu that are found in Igboland in South East Nigeria are not related. The Osu in Igboland, Nigeria are regarded as outcasts and seen as the forbidden group at a time but that is changing. Though they are Igbo, the major groups don't allow their children or families to marry from this sect and disloyalty to this unwritten laws many years ago used to come with grave consequences. The Osu are not supported to hold political positions etc. Although the reality is there but everyone shy away from discussing this.
The Osu were victims of local slavery dedicated to the service of their owners or slaves of particular deities.
Today, many of their descendants are in great position because of the missionaries activities to liberate them many years ago. They had pity on them and majority of them became Christians and they were educated. Despite their achievements, the stigma still persists but it's getting better as individuals, groups, government and churches frown at this caste system.
So many Osu from Igboland lives in South West Nigeria and married people from other ethnic groups.
