Taylor Carl Bendix Togstad in America

I am trying to trace the brother of one of my ancestors, who moved from Bergen, Norway to Lüneburg in Germany around 1819, but then possibly emigrated from Germany to America in 1851. Carl Bendix Togstad was born in Bergen on November 4th 1798, with parents Andreas Togstad and Margrethe Gregoriusdatter. His father was a master taylor, and Carl Bendix himself is a taylor's apprentice in the 1815 census. At the time of his father's death in 1837, Carl Bendix had (according to the probate records) been living in Lüneburg for the past 18 years. In Germany I have just one single possible trace after him, as a Schneidergeselle (taylor journeyman) Togstadt in Lüneburg is listed as an emigrant to America in 1851. If there are any other traces to be found after him in Germany or the US, I would be thrilled to hear about it. In Norway I have already covered the ground extensively.
