There were three Russian ruler named
Vasiliy, or
Basil in English. One was
Ivan the Terrible's father. For me, if I see two Russian names together, I want to put -ovich or -ovna on the second name, since in Russia they use a patronymic and those are the endings. So, for
Miroslav Alexei, I'd keep saying
Miroslav Alexeevich (
Miroslav son of
Alexei).
Ivan's name was
Ivan Vasilievich. For the
Vladimir nn, it's
Volodya.
