Where did you find that map? It is very unusual to find a map showing property ownership and the HSWT would love to have a copy with permission to reproduce it. Do you have access to similar maps for Winslow Township?
You can thank RednekF350 for bringing this thread back to the surface. I had totally missed your recent added postings to this old thread.
If your interest is Winslow Township, cadastral maps for that locality extend back in time to 1850, when R. Pearsall Smith published a regional map depicting a portion of the area around Philadelphia and extending well into New Jersey. Barnes & Van Derveer published a cadastral map of Camden County in 1857, followed by the Lake and Beers map of Philadelphia & Vicinity in 1860. The so-called Walker School District Map of Camden County, published in 1877, is also cadastral in nature. The detail of the map shown above is from circa 1935, when the Franklin Survey Company published a cadastral map of portions of Gloucester, Camden, and Burlington counties. There are also manuscript maps available for Winslow Township, including ones prepared by John Clement, the best collection of Camden County surveys from the nineteenth century. I also have a copy of a map of Winslow Township that New Jersey State Highway Department surveyor Harry Marvin annotated back in the 1930s. Harry often worked with Charles Boyer on subjects like old roads, etc. I am sure other surveys and manuscript maps exist for Winslow Township, but these are the ones that come immediately to mind without madly ripping through my flat files looking for additional examples.
