My great-grandfather, Gottlieb Henschell, born June 1860, always gave his place of birth as near Stettin, which is now Szczecin, Poland. However on his naturalization papers he cites "Kunyon, Russia" as his birthplace. Of course, this is probably a phonetic spelling. He was ethnically German and his family may have been Volhynians. Is the place name - or a similar placename - familiar to anyone?
