It is not farfetched that Trinis with French and French sounding names may have had a parent or parents from either Greneda, Vincy, Loosha, Dominica. Many of the "white" Trinis are descendants of Martinique, Guadeloupe and Haiti. Remember this started first with the Spanish authorities in Trini issuing the Cedula de Populacion.
This Foreign/local things is a bit petty. As far as Shaka is concern, I think Shaka was born in England because his dad was studying there. Isn't that the case. At what age he came to Trini. That I don't know. There is no record of him playing for any youth club in England before he came to Trini. It appears that he learned and played the game in Trini until he went to Howard Univ. Compared to.Samuel who was born in Trini. There is no record of him playing primary, secondary schools or youth football in Trini. It appears he learned the game thru the English club system.
