Among the Batelela in the Sankuru region of central Congo the word for stranger is ongendagenda. It is also one of the most common names for a male child. The reasoning is that when a child is born - and males matter most among the Batelela - he appears from nowhere and is unknown, so he is usually called Stranger, and this name stays with him throughout his life - Stranger is the "John" of the Sankuru region.
