We have a grandfather who left no information about his parents. All we have is his naturalization petition. He is Herman Platzke, born 14 August, 1880 at Danzig, Germany.He arrived in Darien, Georgia, USA, 5 March 1899 on the commercial ship SS Limor from London, England. He was part of the ship's crew, and worked as the ship's carpenter. He became a US citizens on 5 February 1919 in Savannah, Georgia. Does anyone have a source for German ships and their crews information?
