No, there are just a handful of Kenyan surnames so they repeat a lot.
it is like asking if all Olsons, Smiths or Jones in the US are related. Chances are they are not.
No relations at all. They come from two different ethnic groups: Conseslus a Nandi and Brimin a marakwet(traditionally good at steeple chase-Moses Kiptanui, Bernard Barmasai etc)
