Is there anywhere I can find some information about Kateregga of Buganda?

[RhoxOS]

Just played Buganda and was curious about this guy.

He received 3 events from the devs but Wikipedia's content is weak and all I could find on google scholar is

"He conquered Butambala, Gomba, Busujju, Singo, and Mityana"

or

"He conquered Ssingo, Kyagwe, Gomba, and Butambala"

I could buy a book but I guess I'm not that curious.

Is there somewhere on the internet that has information for him or is this a thing that needs delving into papers and professional books?

Thanks in advance
