Unfortunately, most people look unhappy in photos from the last century. :-(
Eric, you made a post wherein you said that Grand Duke Paul and Princess Paley had a house in France were they lived while in exile, but could return after the revolution. I am sure that you meant Princess Paley could return there as Grand Duke Paul was murdered in January 1919 outside the Fortress of St. Peter and Paul.
Did Princess Paley have the funds to return to their house or was she as destitute as most exiles?
As to Marie Pavlovna, I didn't like her much when I first read about her, but over the years, I have come to see her a little differently. I don't think I would have liked to have to fight against her as Alexandra did.
