Professor Mũriũkis list must be given precedence in this area as he conducted extensive research in this area starting 1969, and had the benefit of all earlier literature on the subject as well as doing extensive field work in the areas of Gaki (Nyeri), Metumi (Mũrang’a) and Kabete (Kĩambu). On top of the ruling generations, he also gives names of the regiments or army sets from 1659 a margin of error and the names of annual initiation sets beginning 1864. The list from Metumi (Mũrang’a) is most complete and differentiated.
