As most of you probably knew, Emperor
Nicholas II of Russia had four daughters, grand duchesses
Olga,
Tatiana,
Maria and
Anastasia, and a son, Tsarevich
Alexei. The daughters were often referred with an acronym OTMA, which was built from the first letter of each girl's name in the order of their births.
If you had four daughters and a son with initials O, T, M, A and A, what would their names be? You can add them any middle names you like, but the first names should start with the letters mentioned.
My OTMA + A sibset would be:
Olga Johanna - Yes,
Olga! It was my great-grandmother's name.

&
Anton Kasimir
