Kuria, Kisii and Maragori - a likely protolanguage?

Here. My friend is from Bonchari. Called Keragori Felix. 😊😊. We orally say Murogori(Muraguri) is brother to Mugusii (Kisii) and cousin to Mukuria (Kuria). If we were to construct Ruragori(Maragori) language protolanguage, we would slightly loose if we go 'Luluhya (ruRuhia)' way.

-: Our Migango clan is what the Gusii call Mugirango. The Gusii don't intermarry with va Migango e Vologooli because they are siblings.

Similarly, the Kirima clan is found in Mumias or Butere Mumias. They also know they can't intermarry with va Kirima of e Vologooli because they are siblings.

-: I was jabbly told that Mugirango was sent by his father, Mugusii to visit Murogori, his uncle. Murogori happily welcomed this son, his son. Telling him that he was doing fine, in this land where he migrated to since he parted with his brother, Mugusii. 

He did not wish Mugirango to go back to Gusii. And here we are. 

- Views?

-: Also find out. Muraguri is a seer. That is why Mulogooli was called Mulaguri because he "prophesied". There name later became Mulogooli. This is also researchable.
