You might find information in the "death memoirs" that Moravians wrote about their lives...to be added to and read at their funerals...like an obituary.The German word for this memoir is (spelling?) liebenslaff (or schlaf).If the records have already been translated from German into English, a copy can be purchased from the Moravian Church Archives for a reasonable amount and a lot of patience.(They don't have many people working there who can copy the information for you.The original records are extremely fragile, so they don't handle them very much or provide translation services for untranslated memoirs.)I am referring to the church in North Carolina.I don't know about the archives in Bethlehem, Pennsylvania.
The records are only as good as the information the person recorded about their life.In the case of my FISCUS ancestors, the memoirs led my mother from NC back to PA through information contained in the memoirs she discovered.Since then, I have received four other memoirs.If nothing else, it helped me to appreciate how much my ancestors were required to sacrifice to emmigrate and build new lives in a primitive environment.
I wish I could give you the address right now, but I know you can locate it from Cyndi's List.Good luck.
