In this three-part series, I will attempt to solve a puzzle that has bothered and intrigued me from the time I first set foot in Jamaica some 20 years ago. What is it about this small island and its people, 6,000 miles from Ireland, hardly the size of the state of Connecticut, and with a population that originated mainly from a different continent, that made me feel so at home? How was it so easy for me -- and so many like me -- to make it my home?
