Hi cando!
Thanks for your response. I have some sketchy information on Johanna. She was born "about" 1838 followed a thread to find she came out here in 1857 on that ship. I am taking this information as true only because others have researched it and filled it in on other sites. She has parents listed as unknown on many sites but that's all I have so far. She did end up in Raymond Terrace where she had an son (Henry) around or before 1858. She went on to marry a man with the last name Martens and her son became often known as Henry Martens after that. I think that's all I have at the moment. Where was the J Helmling you saw?
