Ivanna

There is no Russian name as Ivanna, in Russia it is Ioanna, Zhanna.
IVANNA is the Ukrainian name, feminine form of IVAN, also Ivanka, Ioanna, Yana, Yanina. [noted -ed]

This name may be extremely rare in Russia, but perhaps it would come in useful to a Russian parent who wanted to name their daughter in honour of a family member called Ivan or perhaps in honour of the mother's maiden name (if it was Ivanova).

I'm Russian, and I have never, not once, met, heard of, or read about a Russian Ivanna.
