The Marachi (Abamarachi) settled near the Nzoia River in present-day Busia County. Oral traditions suggest that the Marachi may have incorporated elements from Kalenjin-speaking groups before fully adopting Luhya identity and the Bantu Luhya language. They are neighbours of the Samia and Khayo, with whom they share close ties. The Marachi are farmers who also engage in fishing along the Nzoia River.
