We all know about nicknames for given names. Dick/Richard, Bill/William, Valodya/Vladimir, and so on. I have a genealogical mystery that can be resolved if the family name KONYAKOV, pronounced KONyakov, not konYAKov, could be a nickname for the family name KONOVALOV. Southeastern Ukraine, early 20th century. Any ideas? Thanks.
