Despite the financial problems of GD Xenia, she left quite a sizeable amount of money when she died. This, despite the fact that George V provided for her, and the fact that she was swindled and lost most of her jewellery. Her living expenses must have been quite substantial, as she had a large house to run, and sons who were probably not having an easy time. How she managed this I cannot imagine, as she was not, by all accounts, particularly good with money.
Her sister Olga, in comparison, was really poor, and I think more sensible in many ways than all the rest of her family. Poor Olga had a really hard time financially compared to her sister. I wonder if George V made any financial provision for her ? I dont think so.
