Founded on the shores of the River Ase, Igbuku is one of the last Isoko towns sharing a common boundary with the UkwuaniKwale speaking areas of Delta State, Nigeria. Igbuku shares a common boundary with Ofagbe, Ovrode, Ibrede, Aboh, and Ashaka. The town is made up of descendants from Isoko and Kwale speaking founders who have so intertwined in intermarriages, that almost everyone from the town can trace to a mixed ancestry. Most early founders were from Ellu, Ovrode, and Aradhe hence most people trace their ancestry to Ellu, Ovrode, and Aradhe. There are also migrants from Ellu, Ofagbe, Ibrede, and Aradhe. Isoko language is the main means of communication, but ukwuani names are common.
