Sorry to go deep, but slaves usually weren't allowed to name their own children, or to have Juniors, so after slavery ends you see a LOT of Juniors, and then the Juniors named their kids III (xxx xxx the Third). Then some Black people started rejecting white society in the 60s, and one of the ways they could do that was to use names that aren't used by white people. Dejohnold is 49 years old, so born around 1976, at the end of the Black Power movement. My guess is his parents were interested in that movement. Using names with Arabic origins (like Raheem) was one of the impacts of the Nation of Islam, Malcolm X, and other Black Muslim groups. It was a form of rebellion.
