Query: Not necessarily a good bang for the buck

While the booklet appears to be interesting in giving some history of surnames and regions from the 15th and 16th centuries, it is disappointing in only providing surnames of a census and no other information. The booklet has a list of researchers and surnames they are researching, but no way of contacting these folks in hopes of a connection. Some of the information in the booklet can be found on the internet at no cost. Seriously think twice before shelling out the $25.
