>>4164482 (OP)Slave owners used to give their slaves Greco-Roman names for gegs. Later the freed slaves thought that those names were black culture and shiit. But since they don't know that those names are Greco-Roman, they just began inventing new ones that sounded kinda similar to the old ones, and after many generations you get LaDarius, Quantavius, etc.
Another subset of negro names comes from traditional African names but, again, very distorted over the years - Shaniqua, Quinshila, etc.
