offers a speculative biography of De Bourbon's purported ancestor Jean Philippe de Bourbon. According to the novel, Jean Philippe was a nephew of King Henry IV, which would technically make Balthazar Napoleon the eldest in line to the French Throne. The author states that he completely believes in his theory, although he does not have absolute proof of it. In 2008, Prince Michael favoured a DNA test, "perhaps from a surviving lock of Bourbon hair", to verify De Bourbon's claim of kinship. De Bourbon stated that he was ready to undergo the DNA test, but that he wanted to know "if the original samples will be available for matching since there were frequent inter-marriages among European royal families."
