In page Grand Duchess Maria Nikolaevna of Russia, Duchess of Leuchtenberg:

"

Grand Duchess Maria Nikolaevna of Russia was born on 18 August [O.S. 6 August] 1819 in Krasnoye Selo in Saint Petersburg. She was the second of seven surviving children and the eldest daughter.[1] Her parents, Tsar Nicholas I of Russia and Empress Alexandra Feodorovna, born Princess Charlotte of Prussia, were devoted to each other and to their children. They were warm and affectionate parents, but avoided overindulging them.[1] In the evenings, Alexandra Feodorovna played games with her children, including riddles and charades.[2] The Tsar liked to sing chorus music with them. Maria was known fondly as "Masha" within the family and with close friends. Maria and her siblings grew up in a close knit family, remaining on good terms all their lives.[citation needed]
