My grandfather, Johannes A. F. Krohn was born in Germany (Berlin) 8/11/1887. His father was Emil Krohn, Germany, and his mother was Marie Falkenhin (Falkenhain), Germany. I am looking for any information on either of these individuals, or other children they may have had in Germany. Johannes immigrated to the US at some time before he was 29. He may have been a sailor on a German vessel and arrived in a port other than New York. I have not located him on any ship manifest for NY during a probable time frame. Any information would be greatly appreciated!
