I am from Kilimanjaro, Tz as well, so what you ‘The Tembas’ are saying is quite true regarding naming children. The case is different to people originating from around Lake Nyanza (Victoria). Each child is named after the festive or season or occassion or anything remarkable that happened during that time which will coincide with the day s/he was born. During my early childhood, I met two brothers, one by the name Wambura Marwa and the other Mwita Chacha, and I asked them, aren’t you blood brothers? they said yes, I asked, why two different sirnames then? then they explained to me what I wrote above. Since then, my thinking changed.

Elimu haina mwisho!
na Kuishi kwingi, [ni] kuona mengi!
