I am searching for information about my Grand Father. He was born in Oldenburg, Neidersachen, Germany, in 1870. His full name was Eirlert Gerhard Friedrich Unger. He had at least two brothers, one named Georg. He arrived in Australia in June 1894 aboard the SS Erlangen out of Hamburg. In Australia he was known as Friedrich. Friedrich's father's name was either Johann or Hinrich, I am not sure which. Anyone with any information about Friedrich and his family in Germany, please contact me.
