Anyone looking for a cool name for their baby boy could not do much better, in my opinion, than Volodymyr.
It means bright and famous ( as does Robert, but it's not the same name).
It can be shortened to Volodyk, Volodia and Vlodko, but I like the idea of Volo.
Or, if you taste is less traditional, maybe Zelensky (or, as they spell it in the Guardian, Zelenskiy).
Stand with Ukraine. Glory to Ukraine.
