In 1847, Nicholas and Clara (Schneider) Wehner emigrated to the U.S. from either Dietersheim, Bavaria (as given in the passenger list) or Fulda, Hesse (as given in a Goodspeed Publishing Co. biographical sketch, to which Nicholas may have contributed). Census data give Prussia and Hesse as birthplaces. Nicholas was the son of John and Flora (Miller or, more likely, Muller) Wehner.
After arriving in Baltimore on 31 May 1847 Nicholas and Clara immediately took a steamship to Louisville and, later that year, went on to Cape Girardeau, Missouri. I have often wondered why they spent some time in Louisville, longer than would be the case if they were merely going around the Falls of the Ohio to pick up a steamship for the remainder of their journey. Did they have relatives in Louisville? Perhaps Albert Wehner? There were several individuals of German origin with the name Weiner, Wiener, Wener, Winner (common mispellings for Wehner) living in Louisville in the 1850s and 1860s.
