J Kroninger,
I have found much about the Dohse's since I posted that message. I am working with five others trying to find our common ancestry. I have not seen the name Sarah Joann but will keep it in mind. The Dohse surname started as Dose and comes from the north of Germany. Myself and the other researchers find that we all go back to a common area of Mecklenburg. We also find that the U.S. Dohse's mostly come from the Ohio area and Kentucky before that. Some of these Dohse's migrated west and were settlers in Oregon. I will keep your search for Sarah in my files.
Regards, Keith
