Does the Wicz suffix have a Cyrillic origin? I've heard that the Wicz suffix denotes Ukranian, Russian, or Belo-Russian origin. Could the translation from Cyrillic to Latin create the Wicz common to many Polish names? I realize my question is vague, but at the moment, I can't think of another way to ask it.
First of all Cyrillic is not a language but a way of writing devised by St Cyril. Endings similar to Polish –wicz to indicate a patronymic (who someone’s fatehr was) are common to all Slavonic tongues. In Russian it is written –вич, by the south Slavs –vić, in Czech and Slovak –viè, in Polish –wicz and earlier –wic (as in Paweł Włodkowic).
All these languages evolved from a common Slavonic root but over the centuries gradually moved away from it and became more distinct. That was also the case with Old English which was much more similar to German than modern English is.
