I guess it must be 40 years old, but it's hard to say. It's quite cheaply produced, and 20 pages long, with a nice cover; more of a pamphlet than a book really:
I confess to ignorance about Zambian names, so this was interesting to me. The author suggests that last names are only coming into use in Zambia at the time of writing, because so much more is being written down.
A man has the name Nchimunya (same) because the one born before him was also a boy. Now that this man is married he takes Nchimunya as his family name and his children will also be called Nchimunya.
Other names relate to circumstances at the time of birth:
Milimo (work) - a child born at harvesting time
Mabvuto (troublesome birth)
Another pattern common in many cultures, and also present in Zambia, is to use the name of a deceased or living ancestor. Perhaps this was sometimes done to invoke the protection of the ancestor (if deceased).
There are also many clan names (as the author calls them). It gives solidarity within the clan and is exogamus, i.e. marriage within the clan is forbidden.
Examples of clan names are:
Bemba Bowa, Bwali, Mbulo, Mfula, Ng'andu, Ng'oma, Nsofu,
Lozi Inambwae, Neta, Namuchoko, Nasiba, Nalikando, Naluya, Ndandula
Tonga Moono, , Mudenda, Muleya, Muzyamba, Mweetwa, Muntanga
Tumbuka Kaluba, Kumwenda, Njovu, Nyirenda, Nyirongo, Phiri, Zimba
Recognising that naming these days is much more open to borrowing from other cultures, the author also lists a number of non-Zambian names. One worth a mention is Lwanga, after Charles Lwanga (died 1886).
One of the 22 African martyrs of Uganda. Lwanga was in charge of the royal pages and baptised four of them, including Kizito, aged 13, whom he had saved from the evil intentions of Chief Mwanga. Mukasa, Kizito, Mulumba, Kagwa, Mawaggali were some of the others who died for their faith. Mukasa was beheaded and the others were wrapped in reed mats and burned to death at Namugongo. (Feast day 3rd June.)
