According to legend, the people of Oro migrated from old Oyo as a direct consequence of chieftaincy dispute that broke out in that kingdom in the fifteenth century.

A man named Olakanmi who was a prince escaped from the Royal household and led members of his family, friends and dissident warriors out of old Oyo.

It was recorded that the Ifa oracle told Olakanmi to move South East of old Oyo and settle wherever he saw a lot of Igi Oro, Eiye Agbigbo and heard the sound of mortar pounding and the presence of blacksmiths with their dexterity on play of the instruments of their trade.

The contingent stopped here for a while.During the sojourn at Idofin Odu, Baba Agba, a junior brother to Olakanmi, and some of his followers led an exploration party during which they discovered the sounds of mortar pounding yam.

Olakanmi was excited about the report and led a party that discovered the blacksmiths, Igi Oro trees in large numbers harbouring hundreds of Eiye Agbigbo.

The Onire family claim to have migrated also from old Oyo as a result of barrenness on the part of his wives and were extremely fulfilled on getting to the location where Olakanmi met them.
