Where is the ancestral home to these good elders?

Good Morning Family, any leads of meeting these cool brothers and awesome elders of Saniaga? I will appreciate any prior information. I am told 3rd left with brown coat is Dr Perez Olindo,

At the middle is Mzee Elisha Musasia
And on the wheel chair is Mzee Naftal Kegode. 

May we all enjoy our day, working smart and with love, being the change we desire at a personal level. 😊😊.
