Perhaps have uncovered a name--Friedrich Gerhard Stahlkamp, who died in Cincinnati, Hamilton, Ohio, USA between 1860 and 1869. Still waiting for more information. There was also an "F. Stahlkamp" shown as a passenger along with his family including M.E ( Marie Elisabeth?), M.G. ( Marie Gertrud? ), among others arriving in New Orleans, LA. USA 19 Nov 1838, aboard the LOUISE.
Anything you can offer to tie these people to Marie Elisabeth Stahlkamp Luebbehusen who married Johann Heinrich Luebbehusen of Oldenburg?
