I just found Marie Simunek born Koudela & her husband, & two children at Ancestry in the Hamburg passenger lists - the lists in German that were just made a available. I had much of this info from the English passenger lists, but not their residence. Another relative- a daughter of a Koudela mother- was born in Ouhrov in 1893.

Marie Simunek

Estimated Birth Year: abt 1836
This places their residence as Ouhrov (also spelled Uhrov), Caslav just before they sailed.
Other Simuneks are liste. I also searched the database by Ouhrov and Uhrov.
