Hi, I got a very helpful map of the townships of Cumberland County from the County Engineer, George A. Schock. It is dated January, 1971. It is very helpful! When I was there last summer I got a map called "Map of Cumberland County New Jersey" published by Cumberland County Board of Chosen Freeholders, Administration Building, Bridgeton, NJ. (609) 453-2125 It's very good! I also got a "Map of Salem County, New Jersey" prepared by the Salem County Board of Chosen Freeholders, 1971. It says on the map: Additional copies may be obtained from the Clerk of the Board of Chosen Freeholders, Salem County Court House, Market Street, Salem, NJ 08079 Hope this helps. Mary Hill
