Good news. The “Map Guide to German Parish Registers – Oldenburg & Schleswig-Holstein” is again in print in the soft cover 
edition. If you have ancestors from the area, this book is sure to be or help in your genealogy research.
Each volumes of the series does the following:
- Identifies the parish where an ancestor worshipped based on where they lived.
- Gives the FHL microfilm number for the family’s parish records.
- Identifies nearly every city, town, and place that included residents.
- Visually identifies church parishes for Lutherans & Catholics in each district.
- Identifies adjoining parishes in case an ancestor attended an alternate parish.
- Aids in area searches, particularly across district or regional borders.
- Provides visual identification of search areas in which to look for a family.
- Helps in determining proximity of one area to another.
- Aids in determining reasonable distances of travel from one area to another.
- Identifies population centers in each parish.
- Identifies archives, repositories, and other resources.
- Aids in identification of the location of minority religions.

My GGF was born in Duchy Schleswig in the 1840s. I do not know the village or town. In what way would this book help me trace his origins?
The Map Guide to German Parish Registers is useful once the researcher has found what the city or town of origin happened to be. Although there is info dealing with archives, etc., the real value of the volumes can only be used once you know the exact place.
Thanks for the response. Are you aware of any active project to transcribe & index the parish registers from Duchy Schleswig to enable searches by name?
