Hello, I just chanced upon your post and I don't know if you've got any information yet. Rupert Gittens became a Roman Catholic priest late in his life, in is 80's after he joined the Dominican Order. I believe he died in 1985. As a historian I know some of the available details about his activities during the 1930s into the 1950s when he and his colleagues were very active in the labour movement as Marxists. They were closely watched by the colonial authorities and the US government. I also understand that in his religious conversion that he was very much influenced by Sr. Aloysius Ashby a religious sister who was his friend. I don't know much else about his life there after but I am curious since I'm working on a historical novel of the period during which Gittens was very active. US State department records from the Port-of-Spain consulate would have information. Hope this helps.
