Many immigrants from the Hessen-Darmstadt area in the 1850's booked passage with Zacharias Demuth of Rimbach. My Nieder-Mörlen and Wald-Michelbach ancestors (the Kempf and Braun families) arranged passage with him on the Ocean Queen (Black X Line) London to New York in Oct 1854. Questions: (1) Does anyone know how these immigrant families traveled from Hesse-Darmstadt to London? and (2) Does anyone know anything about Zacharias Demuth's business? Thanks ...
