My great grandfather's marriage certificate was translated for me. It says he was from Gross Kalinkowo, district (R.B. = Regierungsbezirk) Koenigsberg, Eastprussia (Ostpreussen). I found out that Koenigsberg is now in Russia. I'm having trouble finding the town, if it is a town. He was actually born in Italy but am assuming this it where his father was from and that they moved back to her. Any help would be appreciated.
