Many years have passed since the death of Princess Diana (31 August 1997), but this tragedy still attracts attention and hurt the hearts of people. Many authors have investigated the mysteries of this tragedy, and the secrets of ancestry of Princess Diana. Some authors claim that her bloodline (by branches of the Stuarts) comes from the mysterious Merovingian from the early Middle Ages - and the Merovingian bloodline supposedly dates back ... to a son of Jesus Christ and Mary Magdalene. From a Christian perspective, it is certainly heretical hypothesis. The author of this brochure puts forward a different hypothesis, which is compatible with Christian doctrines. The study of mysticism matches of various aspects of tragedy the death of Princess Diana and analysis of what is known about Mary Magdalene - all this led the author to unexpected conclusions that confirm the origin of the Merovingian (and the bloodline of Princess Diana) of the kings of ancient Israel, David and Saul, but the author's conclusions are compatible with Christian doctrines. *** Author BORIS ROMANOV Born in 1945 in Leningrad (St.Petersburg), Ph.D (the candidate of sciences), the writer.
