Nice and very visual video about Grand Duchess Olga Alexandrovna (~52 min).
From the Romanov Royal Martyrs channel at youtube.
"The extraordinary story of Tsar Nicholas’ sister and her journey from the palaces of St. Petersburg to death in obscurity above a barbershop in Toronto. A life full of passion and love, set at the backdrop of an entire century. She was raised at the Gatchina Palace outside Saint Petersburg. Olga was her father’s favourite, but Tsar Alexander III died when she was only 12. After the Russian Revolution, Olga escaped to Denmark with her second husband and their two sons, in February 1920, where they lived as farmers. Finally, in 1948, she relocated with her immediate family to a farm in Campbellville, Ontario, Canada. At the end of her life and afterwards, Olga was widely labelled the last Grand Duchess of Imperial Russia."
