My great grandfather Frederick Blume was born in Leimberg, Hanover in 1842. He was the son of Christian and Catherine Blume. He came to Australia as a stowaway in 1862. Siblings include Conrad Henery who had come to Australia a couple of years earlier.There was also a Sophie who came to Aust and others, names unknown who stayed in Germany. Am interested in the German connection or any clues as to how this could be followed up.
