Romanov extended family group, 1896
Standing at the back from left to right: Ferdinand, Crowned Prince of Romania, Nicholas II, Grand Duke Sergei Alexandrovich, Princess Victoria Melita (standing very far from her husband, Ersnt Louis, Grand Duke of Hesse and By Rhine.)
Sitting in the middle row from left to right: The little boy still in skirts holding hands with the lady next to him, Marie, Crowned Princess of Romania, is Grand Duke Dmitry Pavlovich. Next to Marie is Empress Alexandra Feodorovna, holding her daughter Grand Duchess Olga Nikolaevna; next to her is Grand Duchess Marie Alexandrovna (I am using her original Russian title, she was also Duchess of Edinburg and eventually Grand Duchess of Saxe-Coburg Gotha.) I do not recognize the baby she is holding. Last, sitting in front of Ernie, is Grand Duchess Elizabeth Feodorovna.
On the floor, sitting by Marie and holding a little girl's hand, is one of Marie's younger sisters. The little girl whose hand she is holding is Grand Duchess Marie Pavlovna, the younger. Her father, Grand Duke Pavel Alexandrovich, is sitting next to her. Lastly, I am very tempted to say that the woman sitting to the right of Pavel is the elder Hessian sister, Victoria, although I am not 100% sure!
