OTMA (cyrillic ОТМА) was an acronym sometimes used by the four daughters of Russian emperor Nicholas II and Alexandra Feodorovna as a group nickname for themselves, built from the first letter of each girl's name in the order of their births:
Ольга - Olga Nikolaevna Romanova (15 November 1895 - 17 July 1918)
Татьяна - Tatiana Nikolaevna Romanova (10 June 1897 - 17 July 1918)
Мария - Maria Nikolaevna Romanova (26 June 1899 - 17 July 1918)
Анастасия - Anastasia Nikolaevna Romanova (18 June 1901 - 17 July 1918).
In childhood the grand duchesses came up with ОТМА as a sign of sibling closeness and affection for one another, writing it in their diaries. The girls were great granddaughters of Queen Victoria and although "thoroughly Russian," grew up speaking both fluent English and Russian among themselves. Whilst the family was in captivity after the Russian Revolution of 1917 they were allowed to send few letters, so the sisters often signed this nickname on cards they had written together for loved ones and friends.According to the official website of the Swedish monarchy, the Royal Family includes the following:
