We can't see the connection. My grandparents came from India to Guyana, where my father, David Meghoo, was born. His parents died when he was a child and his step mother brought him to Jamaica when he was about 13 years old. They did live in the Clarendon and St Catherine areas and also in East Kingston, but none of my family know of any Meghoo's in the Cockburn Pen area, nor do we recognize any of the names you have listed.
Will keep your emails and if we ever do find a connection we will contact you immediately.
Thanks very much
