A database of German emigrants from Baden, Württemberg and Hohenzollern has been updated with English pages. The German version wasn't that hard to figure out, but this really simplifies searching, as well as learning more about the project.
I did not find August RICK or the MÜLLER family, but that may be because they did not have permission to emigrate -- like the site notes, these individuals did travel to Le Havre, France to board a ship. I did find several RICK family members from Siegelsbach, though. I haven't spent much time looking for these folks in American records, but will eventually.
