Throwback Times Nigeria is here once again to dissect the genealogy and complete verified list of Umudioka clan settlements in modern Nigeria. Long before the amalgamation of Nigeria in 1914, the Dioka (Umudioka) clan had established a remarkable presence across several parts of Igboland through migration, trade, healing, craftsmanship, and social integration. Oral traditions trace the clan's ancestry to Dioka, fourth son of Dunu, a descendant of Nwa Okofia, the ancestral figure from whom present-day Dunukofia in Anambra State derives its name. The Dioka people became especially renowned for their mastery of Igbu Ichi (traditional facial scarification), a respected profession that contributed significantly to their movement and settlement across numerous communities. Some migrations were also linked to trade, apprenticeship, and the historic Ije Osu institution.

Historical accounts and oral traditions identify the following settlements associated with the Dioka (Umudioka) clan across Igboland and neighbouring regions:
