They are a result of intermarriages between Banyoro and Baganda supported by the British Empire.
As a token of appreciation, Kabaka gave Namuyonjo control over the captured county of Bugerere, which was predominantly occupied by Banyoro.
Namuyonjo did not occupy Kayunga at the time because the area was infested with dangerous flies known as "embwa".
It was not until Buganda, helped by the British, flushed out the flies, that people started living in Kayunga.
Namuyonjo proceeded to Budali, Bugembo, Kitwe and Bbale villages.
Since Koojo was not from the royal family, he was forced to surrender his leadership mantle to Namuyonjo without any resistance.
The "Batumbugulu" are the Banyala that came to Bugelele long after Namuyonjo had overthrown "Mukongo".
The Banyala are found in Central part of Uganda, in Bugerere, Kayunga District.
They too carry out trade with the neighbourhood in fish, charcoal and food.
They too grow millet, g-nuts, yams, cassava, and other kinds of vegetables.
Their land is very dry almost all months but they do farming near the shores of lake Kyoga.
The Ssabanyala heads the clans of the Banyala, their customs and traditions.
[6] The naming of children among the Banyala is based on proverbs, seasons and clans.
When a Muinyala lost a family member, the bereaved built a hut around the grave.
In addition to being Roman Catholic and Anglican around 7.3% of Banyala are Pentecostal.
Many still follow traditional religions, and there is a high level of syncretism among those who go to church.
