Marie Alexandrovna, only daughter of Tsar Alexander II of Russia. She married Alfred, and became Duchess of Connaught. At first, Victoria was not fond of this daughter-in-law, and Marie returned the favour. And Marie loved rubbing the fact that she was born Imperial in her mother-in-law's face, with her jewels and personal wealth being greater than Victoria's. But Victoria privately admitted that she admired Marie for standing up to her.
