OTMA


OTMA was an acronym sometimes used by the four daughters of Emperor Nicholas II of Russia and his consort, Alexandra Feodorovna, as a group nickname for themselves, built from the first letter of each girl's name in the order of their births:
Note that the Roman and Cyrillic forms of all four of the initial letters are identical in printed form.
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. 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.
