Hey sorry for answering 3 days later!
As a person living in Poland all my life I think no young girl would like to be named that. It is dated indeed but it’s also like a meme name, something like the “Karen meme” in States. [name_m]Janusz[/name_m] and Grażyna are like a stereotypical polish couple who wear socks with sandals (lol), love to pick up the bargains, [name_m]Janusz[/name_m] drinks beer and watches tv and I don’t know what else… It is very possible children with these names would be teased and called names like: “Janusz of business”, “Grażyna of bargains”. It might sound neutral but in Polish it’s hilarious. Like, when you bought a nice shirt on sale and you show it to your friends, they might say: “Ale z ciebie Grażyna promocji!!” (“You’re such a Grażyna of bargains!!”) and burst out laughing. Other meme names in Poland are [name_f]Julia[/name_f], [name_m]Sebastian[/name_m] (Sebix) and I think [name_f]Karyna[/name_f] and [name_m]Oskar[/name_m].
You speak Polish? How come? I think I wouldn’t want to learn it if I wasn’t born here lol
