My third great grandfather was Adam Gottfried Harrach of Sondershausen and Leipzig. He and his wife Rosanna came to Philadelphia in 1800. He was a carriage maker and I have his certificate of training that he brought with him. I have never been able to trace his family and found the Harrachs of Austria to be less than helpful. I was told that Adam was probably a servant and took the name from the Harrachs(a possibility). Not speaking German is a drawback in pursuing this family. Any suggestions would be welcome.
