The very excellent Tudor Parfitt whose work I have been following for about 30 years gives an overview of his fascinating DNA trails. If you can catch his programmes on PBS do so. Also check out his recent book Black Jews in Africa and the Americas. Looking forward to his new project studying the “Conversos” and early Jewish life in the Americas following Spain’s first expeditions to the New World in the late 15th and early 16th centuries. Also listen to him talk (2nd video) about his latest jaunt to Papua New Guinea.
