Chief Suberu Adebule was born around the mid-19th century in Ijebu Imusin. His father was from Erawon, Ijebu Imusin; while his mother was from Oke Fadabi in Odo Aseri in Ijebu Imusin and Okepo. Chief Suberu Adebule migrated from Erawon to settle at a place called Okepopo, Ijebu Imusin, alongside his two brothers and a sister. They built a very big house with 10 rooms there. The house was called Akoka and was the only one in Ijebu province at the time. His mother, called Osunnaike, later died in 1929 at Okepo and was buried there.
He was among the judges in the high court in Ijebu province called Oba Marun. He was diligent, trustworthy, and very kind to his people. Because of the role he played at the Oba Marun court, he was chosen to be the first Baale of Okepo in the early 20th century and he ruled from 1922 to 1953.
He started Olun Omo Onimusin in 1922 to bring together all the sons and daughters of Ijebu Imusin. The system broke down in 1934 when there was a misunderstanding among them. It was later reconvened in 1944 by Chief Suberu Adebule himself.
During his reign as the Baale of Ijebu Imusin, ‘Regberese’ was established and there was peace and harmony in the land. Being a powerful ruler, he had control over the communities and all the Obas in the towns and villages in Ijebu Imusin. People from all walks of life came regularly to visit him.
Being a practicing Muslim, he was nominated as the Ekerin Adinni of Ijebu Imusin. He had a giant-sized wall clock in his home which people from Ijebu and environs came to see. Chief Suberu Adebule was a consummate tailor by profession. He had many wives and children. He died in 1953 at about the age of 120 years on an Ileya day.
