Most black central american players from Honduras,Panama,and Costa Rica with English names have Jamaican links. This according to former Costa Rican captain Juan Cayaso. The Drummond brothers that played up to recenty, Mauricio Wright, and teh little guy Scott on Costa Rica have acknowledged their connections to Ja. On Panamas team, Roberto Brown once wanted to play for JA, Philips also acknowledged his links to the island.
That is true to some extent. But there is also people from other parts of the Caribbean that settled in Central America as well. In Guatemala for example, you have blacks on the Carribbean coast that are descendents from St Vincent. In Costa Rica, on the Carribean coast there, the people are of Jamaican descent and so is the case in Panama, although in Panama there are also blacks who are of Bajan descent as well so there you got both.
I don't think that in the case of Honduras and Nicaragua, there are people of Jamaican descent there, maybe from other smaller carribean islands, but that's debatable.
