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:

• Ольга – Olga Nikolaevna Romanova (15 November 1895 – 17 July 1918) was the eldest daughter.
• Татьяна – Tatiana Nikolaevna Romanova (10 June 1897 – 17 July 1918) was the second daughter.
• Мария – Maria Nikolaevna Romanova (26 June 1899 – 17 July 1918) was the third daughter.
• Анастасия – Anastasia Nikolaevna Romanova (18 June 1901 – 17 July 1918) was the youngest daughter.

Note that the Roman and Cyrillic forms of all four of the initial letters are identical in printed form.
