Your arrival to this country was not by air, nor in a personal cuddy aboard a luxury yacht. West Africans were captured or sold to slave traders who forced them onto slave ships. By forced migration, not immigration, your ancestors miraculously survived a six-eight week voyage while chained to fellow Africans in the hold of a ship like sardines in a can without an inch in between.  The ship exponentially surpassed its occupancy limit resulting in disease and the death of many.  You are a direct descendant of the fifteen percent of captured slaves who survived the voyage.
