I suggest you look carefully at death certificates for anyone you are trying to research. Many German families settled in largely German communities in America, and usually there are church records of subsequent marriages, births and deaths. In many cases they are written in German in longhand, so you need to either read them with great care, or get someone to translate them. Often they will mention the name of the home town or village as it was passed along through family members. Once you have the exact place of origin you may be able to find microfilm records from Salt Lake City. You may have to look for another town nearby if the village did not have a church. Search for the town with the church in the LDS publication base. Again the records may be in German, and almost certainly in longhand, so it takes some practice to read them well enough to understand what they say. This is how I was able to successfully research my own family origins, from the mention of the village in the death certificate for my Great Great Grandfather who had emigrated. Also check to see if there are notes in any family bible which may be available following immigration.
