Anna and Ganna (ukr.) Have two different names?
The name Anna and Ganna are the same. The only difference is in "nationalism". I live in Ukraine, but I like the name Anna more than Ganna, and I wrote down my daughter Anna (in Ukrainian) on the birth certificate. I know one woman whom everyone in the village calls Galya, and according to her passport she is Ganna. So, as you teach the people, they will call you)))
This is the same name, only with different national pronunciation. And there are many such examples in any country. Here the matter is that the names are adjusted to the national language, so that it is easy for a person to pronounce it. Not for nothing that all foreign names are perceived with us with difficulty.
