Gosensgro8,
If you go to Banatbooks.com and click on draft family register you will find a draft of a family book which conains data on the Hepp family in Castor. Peter Hepp came orgionally from Johannisefeld in the Banat via Josefsdorf. Do you have a death date for his wife, Elisabeth Mayer? If you are interested in family history of Germans from the Banat you might consider subscribing to the Banat mailing list at rootsweb.
