> Researchers exhumed Nicholas's father Alexander III — himself assassinated in 1881 — to prove "they are father and son." Alexander III was Nicholas II's father. He died in 1894 of illness (I don't see any hint of assassination). The Alexander who was assassinated in 1881 was Nicholas II's grandfather, Alexander II. Which body got exhumed?
