Onayelu and Ofiran -Oye were brothers and Sons of King Oshinmore the then Awujale of Ijebu Ode.  Onayelu was the elder brother while Ofiran Oye is the younger of the two. In those days Onayelu goes to Ijebu Igbo to hunt on daily basis, during one of his hunting days their father King Oshinmore the Awujale of Ijebu Ode had died but before the arrival of Onayelu from his hunting exploration his younger brother Ofiran Oye had usurped the power of the royal throne. This caused a lot of rift between the two brothers as Onayelu was determined to claim his royal birth right from his brother Ofiran Oye who had now been crowned the new Awujale of Ijebu Ode. Onayelu was later persuaded by their people to establish his own kingship at Ijebu Igbo his hunting abode Ijebu Igbo is therefore founded by King Onayelu Ijebu Igbo .
