The head of the clan is Namuguzi Ssebuganda and the name Namuguzi means the buyer. It came about when Ssegamwenge son of Ssebuganda went to Bunyoro Kingdom as part of the entourage that accompanied Prince Kalemeera into Bunyoro. Kalemeera had gone to get help from Bunyoro's royal family (to whom Buganda's royal family was related) in settling a case he was accused of having comitted against Walusimbi, the then Katikkiro. While in Bunyoro, Ssegamwenge bought many hoes which he brought back and sold in Buganda. On seeing the many hoes he had bought, the Baganda named him Namuguzi.
