↑The current Babukusu of western Kenya are believed to have migrated from the Bamasaaba, particularly from areas around Bubulo, in current Manafwa District. Many clans among the Babukusu have their origins among the Bamasaaba, a testimony to this linkage. Masinde Muliro, once a veteran politician and elder of the Babukusu from Kitale, was from the Bakokho clan, with its base at Sirilwa, near Bumbo in Uganda. Other clans common to both sides include Batiiru Babambo, Baata, Bakitang'a and Batiiru. There are other clans whose names, however, that are only on one side, such as Babichache and Balonja who are mainly among the Babukusu. The common cultural ties are a further indication of close relations among the two sister ethnic groups. During the Constituent Assembly that led to the 1995 Constitution of Uganda, Mulongo Simon, a Delegate from Bubulo East, introduced Babukusu as one of the ethnic groupings of Uganda, acknowledging the fact that both groups, Bamasaaba and Babukusu are intertwined.
