Hello Vonnie, at the moment I am stuck with research for 'my' Dittrich. My 'oldest' Dittrich are from Mittelsteine/Glatz/Silesia. I quite dont belive that this is their origin. I only can guess that they moved from the Hungaria/Austria area to Silesia. But many Dittrich families come from Moravia! Look at www.familysearch.org, you might find something.
I hope to visit the local LDS center soon , they do have films from Mittelsteine. Greetings
