Kdzhv

Sorry, but the name "Кдыжв" is neither a real Russian name nor, apparently, the name from any other widely spoken languages with such original and unusual combination of letters. It is likely a typo or a made-up name. However, if we were to look for a name that sounds closest, perhaps you meant something like **Kiryll** or **Kiryll** (Kiryll with stress on the second syllable). But this is just a guess, and the name "Кдыжв" itself has no meaning, origin, or other characteristics.
