I have more information about each Enrest Vienop of Napa, California. They were certainly looking for a better life and I do think that they found it in Napa.
Here's a quick family tree of the Vienop's who came to Napa, CA and their immediate ancestors..................
Ernest Vinup (Prussia/Germany)
Anne Marie Ilsabein Gurges (Prussia/Germany, Missouri, Nebraska)
Fred Vienop (Prussia/Germany, Missouri)
John Henry Vienop (1850) (Prussia/Germany, Ohio, Nebraska)
John Henry Vienop (1862)
Ernest Julius Vienop (son of Fred)
John Henry Vienop Jr. (son of John Henry 1862)
Ernest Henry Vienop (son of John Henry 1862)
Mary Vienop (daughter of John Henry 1862)
Minnie Vienop (daughter of John Henry 1862)
George Vienop (son of Ernest Julius)
The above is certainly not complete as I have not indicated the wives, or all of the children of Fred and have not indicated John Henry 1850s many children. What it does illustrate is the family connection of the 3 Ernest Vienop's of Napa, CA. As I've written out previously, there were ten original Vienop's to come to Napa. Eight are indicated above. The other two were wives of John Henry Vienop 1850 and Ernest Julius Vienop - Anna Marie Koch Vienop and Fredericka "Ricky" Schiffman Vienop, respectively.
