Hi, My name is Anatoly Gakenberg.There is no such German name: Russians don't have H in cyrillic alphabet.It is misspelled Hackenberg.My ancestors got settled in Ukraine presumably in the 18th century. I was able to find this link in Odessa, Ukraine archive: http://odessa3.org/collections/war/dai/link/luebeck.txthttp://odessa3.org/collections/war/dai/link/luebeck.txt
