Was your Immigrant Family originally from Jöhlingen, Baden Württemberg (Germany)?http://www.odessa3.org/index.html
How is your German? You might need an online translator? I personally prefer Bing Translator. Google.com search for place name above + archives.
Another option is looking into LDS Directory of Archives for the Place Name: https://familysearch.org/search/catalog/957126?availability=...
