In the early days child mortality was quite high and superstition rampant hence the use of such names,methinks. Today child mortality is not only very low but its also unlikely a couple will seek to replace a lost child with a new born.

But even in those days it the use of such names was optional.... One was free to use the original name or forgo "replacement"

The thing that bothers is that most of us prefer ozungu names to our tribal names. Ephantus sasa ni jina ya aina gani...

Wewe fanya hivi... zaa ndio uName watu ukiona kuna gap mahali... sisi tutaitana shanikwa na Tanya e.t.c.

While us Kisiis,our names mostly have no real meaning ,for instance Oigara (sigara),Emamba (mamba),Omoro (omollo),Getoi (toy),Esese (dog),Egesa (saa),Ondieki (fisi)...no meaning at all.
