Twenty-one returnees on Saturday arrived in Yambio transit camp from Khartoum.
The returnees came by lorry, Anisa Radio reported.
Peter Carmelo Baika, the head of the family of five, said they spent two years and half since they left Khartoum in June 2011.
He said some of them lost their relatives and properties during the long journey.
Mariata Khanido Dangu, a returnee from Ezo County, thanked God for reaching home safely.
The State Relief Coordinator for Yambio County Francisco Francis Hakim said the authorities asked the returnees to trace out their places of origin in the state.
