Ancestor Tracks has recently (2020-2021) extensively revised six of our seven atlases in the Early Landowners of Pennsylvania: Atlas of  Township Warrantee Maps of ___ County.  We added information from online surveys as well as from county Warrant Registers and Patent Registers.  The older editions are available in print, but the new editions are only available in pdf file format (immediately downloadable from the linked county webpage below, or on flash drive available from Closson Press). 

To learn about the Pennsylvania Land Acquisition process that England set up to distribute colonial land (which basically continues today), as well as the boundary disputes (between Pennsylvania and Maryland, Pennsylvania and Virginia, and Pennsylvania and Connecticut), Revolutionary War Donation and Depreciation land, and land opened through treaties with Indians, see our Land Acquisition page.

We have also broken each atlas into chapters for those people who prefer to download 1-2 specific townships rather than the entire county from the linked county webpage below.  Each chapter (one per township) of each atlas can be downloaded as an individual pdf that includes all the maps in each atlas chapter, survey book references to online surveys, charts with transcriptions of all information for each individual tract, footnotes from county history books and other sources, an extensive introduction, and an every name index. Remember to watch for allied families who appear in adjoining townships.

Berks, Dauphin, and Lancaster County atlases now include the geo-referenced maps showing the original tracts superimposed over current roads formerly available only on a companion CD at separate cost. The three western-most counties (Fayette, Greene, and Washington) do not include similar geo-referenced maps because they do not have GIS departments who could do the work for us. However, we have looked up and added hundreds (thousands?) of Survey Book references in relevant Warrant Registers that were missing from previous editions so that you can access the online surveys using those references.  We made minor revisions to the Westmoreland County atlas but it is essentially the same as the 2007 version.  The Detailed Tract Maps (353 of them) that we purchased from the the Westmoreland Co.  mapping department (formerly only available on CD at a higher price) are available for $4.99 as a separate download from the Westmoreland county page below.
