Antonia Minor
After the death of the Empress Poppaea Sabina, Nero's second wife, Nero asked Antonia to marry him. When Antonia refused, Nero had her charged with an attempt of rebellion and executed. She was the last living grandchild of Nero Claudius Drusus and Antonia Minor, from whom Nero also was descended but one generation more distantly (i.e. their great-grandchild).
