there is a name called Kadimu bay in Siaya, kenya. However, there is also a historical figure called Dimu who seems to be related to the Luo. What is the link between the Egypt Dimu and the Kenya Kadimu?
The Egyptian word hadoma means "throne/ footstool"
–Demotic htm
Kadimu is Ethiopic Semitic for "first."
2) Kadimu is also a Swahili word.
Here's a line of Swahili poetry:
Yallah mwenyi ezi / mola wa kadimu
Allah, I confess me, Eternal Lord, I pray
3) As far as the Luo Dimu goes, the Luo spoke a Nilotic language.
Dimu means to descend in Nilotic.
Very widely, in Eastern Bantu, ancestors or spirits of the dead are referred to by the common term, dimu , which is probably proto-Bantu.
Given the timeline and location of all 3 of these things, I don't see any apparent connection. Aside from the surface similarity of how these words sound, what makes you think that these three things are related?
