Olga and her grand daughters are beautiful, do you have a mini run down on the grand daughters and who they married?
I'm not Rearden
but I hope I can help with this, too.
Princess Helene married the Crown Prince of Rumania, Carol. Their marriage was a disaster. Her son is the current ex-King Michael.
Princess Marina married the Duke of Kent. Her two sisters, Olga and Elisabeth, married Prince Paul of Yugoslavia and Count Theodor of Toerring-Jettenbach respectively.
Princess Katherine married morgantically to an english gentleman named Richard Brandam. She was the last surviving great-granddaughter of Queen Victoria.
Princess Sophie married first to Prince Cristoph of Hesse and then secondly to Prince George William of Hannover.
Princess Theodora married the Margrave of Baden, Berthold.
Princess Cecilie married Georg Donatus, Heriditary Grand Duke of Hesse.
Princess Margarita married a prince of Hohenloe-Langenburg.
Princess Irene married the Duke of Aosta, Amadeo.
I'm pretty sure I am missing other granddaughters but these are the only ones whose marriages I know of.
