Dee,
I also have an ancestor named Jakob Dittrich. He is my gggrandfather. All I have are some sketchy notes I found in my dad's desk after he passed away. According to his information, this Jakob was born in approximately 1870. His father's name was Franz, and he had siblings named Kaspar and Elisabeth. Jakob had five children: Stefan, Josef, Johann, Michael, and Maria. It doesn't seem to be the same person, but perhaps they were somehow related.
My ancestors lived in Brestowatz in the Banat. (There is also a village by that name in Batschka. ) I'm not certain when they settled there. The family remained there until the end of WWII, then lived in Austria before coming to the United States in 1956.
If you have any more information, i'd love to hear from you.
