Lancaster County (county seat at Lancaster) was created in 1729, the fourth county in the state.

	1720.1 AMPLISSIMAE REGIONIS MISSISSIPI SEU PROVINCIAE LUDOVICIANAE..., by John Baptiste Homann (McCorkle #720.1), this map appears in various Homann atlases. It shows the entire eastern United States and is based upon the De l'Isle map of 1718 with New England added. Pennsylvania is confined to the area east of the Susquehanna. The image here is from a later edition of the map dated circa 1763 by the Library of Congress from where this image comes. A version dated circa 1730 is at the Darlington Library.
	1720.2 A NEW ACCURATE MAP OF THE ENGLISH PLANTATIONS IN AMERICA AND OF THE LOUISIANA AND RIVER MISSISSIPI. London sold by R. Dunoyer in the Strand & A. Rocayrol in St. Martins Lane (McCorkle #720.3), from The Political State of Great Britain, vol. 19, 1720.
	1721.1 A MAP OF LOUISIANA AND OF THE RIVER MISSISSIPPI: this map of the Mississipi is most humbly inscribed to William Law of Lanreston, esq. by Iohn Senex. This map is from John Senex's A new general atlas, containing a geographical and historical account of all the empires, kingdoms, and other dominions of the world, 1721. 'Pensilvania' just barely makes it onto the edge of this map of the middle United States. It can be seen at the Hargrett Library Rare Map Collection - Colonial America and also at the Library of Congress, from where this detail of the Pennsylvania area comes.
	1721.2 NIEU ENGELAND NIEU YORK NIEU JERSEY EN PENSILVANIA DOOR H. MOL., from a Dutch printing of John Oldmixon's 1708 history (McCorkle #721.1). There is also a 1744 German version (McCorkle #744.6).
	1721.3 NIEUWE KAART VAN VIRGINIE EN MARILAND DOOR H. MOL., from the Dutch printing of Oldmixon as the map above. Like the 1708 version, this map extends past the 40th parallel and includes a slice of southeastern Pennsylvania. The map can be seen in Papenfuse & Coale; and as with the map above, there is a 1744 German version.
	1722.1 A MAP OF CAROLANA AND OF THE RIVER MESCHACEBE, from A Description of the English Province of Carolana by Daniel Coxe, London 1722, (McCorkle #722.1, also reproduced in Brown, No. 11, where it is dated 1726; there were several editions). Carolana spreads from Texas to the Appalachians in this map, one of the first English maps of the Mississippi River valley. Coxe was the holder of an annulled land grant to Carolana which he believed stretched from the mountains to the Mississippi. Pennsylvania and all the other colonies are pictured as coastal holdings. He persisted for years trying to establish his rights, including the making of this map, all for nought. This map may also be seen at the University of Virginia site Exploring the West from Monticello: Chapter 2 .
	1723
	1724.1 NOVA ANGLIA SEPTENTRIONALI AMERICAE IMPLANTATA..., from Homann Heirs and may have appeared earlier (McCorkle #724.1). Only the eastern sliver of Pennsylvania makes it onto this map and the state is not named, though Philadelphia is named. This map is reproduced in Portinaro & Knirsch dated 1725.
	1724.2 A MAP OF THE COUNTREY OF THE FIVE NATIONS BELONGING TO THE PROVINCE OF NEW YORK AND OF THE LAKES NEAR WHICH THE NATIONS OF FAR INDIANS LIVE WITH PART OF CANADA TAKEN FROM THE MAP OF THE LOUISIANE DONE BY MR. DELISLE IN 1718. This map appears in Brown, No. 13, dated circa 1730 and called a manuscript map, and as the title says, is based upon Delisle's map. It is also in Swift (2001) dated circa 1723-26, where the original in the Public Record Office, London, is shown. The map is dated 1724 in Schwartz & Ehrenberg and called an engraving which it appears to be. The region covered by New York, Pennsylvania, and Maryland west to Lake Michigan is shown. Rivers are indicated. The portage from Lake Erie (also called Orswego on the map) to the Allegheny is called 'Carr. Place'. There is no other detail. The map lists many Indian tribes though none are named for Pennsylvania. This map appeared in Colden's Papers Relating to an Act of New York for Encouragement of the Indian Trade, New York 1724. The map which appears in Colden's 1750 history is based upon it and this image is from a modern reprint of Colden's The History of the Five Indian Nations of Canada, published in London 1747, 1750.
	1725.1 REGNI MEXICANI NOVAE HISPANIAE LUDOVICIANAE, N. ANGLIAE, CAROLINE, VIRGINIAE, ET PENNSYLVANIA, NECNON INSULARUM ARCHIPELAGI MEXICANI IN AMERICA SEPTENTRIONALI ACCURATA TABULA, by J. B. Homann. A view of southern North America with the political divisions as dictated by the Treaty of Utrect in 1713. This map falls outside the definition of a Pennsylvania map used here but has the name in the title. The state barely shows, but the chance to include a map with both Mexico and Pennsylvania in the title can't be missed. The bottom left section shows a naval battle off the southwestern coast of Mexico. This map is reproduced in Portinaro & Knirsch and dated 1725. A copy at the Darlington Library is dated circa 1737.

	1726.1 A NEW MAP OF LOUISIANA AND THE RIVER MISSISSIPPI. This anonymous map was seen at auction and attributed to either the pamphlet Some Considerations on the French Settling Colonies on the Mississippi (1720) or The Memoirs and Secret Negotiations of John Ker Containing Material on Louisiana and French Empire in America (1726), both of which apparently contain essentially the same map but with slightly different cartouches. However, given its title, the map would seem to postdate the 1721 Senex map above. The map shows much the same region as the Senex map, i.e. the middle United States from Lake Ontario past the Mississippi, but it is a different map and extends further eastward. All of Pennsylvania is shown and boundaries are drawn confining the English colonies to the coast reflecting French opinion.
	1727.1 DRNUGHT OF THE SUSQUEHANNAH RIVER, made by Isaac Taylor Surveyor of Chester Co. A facsimile of this manuscript map appears in Hanna dated circa 1727, which is the image here. It appears to show the area from Harrisburg to Sunbury, where a number of Indian villages lay. The same map appears in a history of Dauphin County by William Egle who dates it as early as 1701. The Juniata River is named 'Cheniaty' and the West Branch is called 'Chimasky or Shamokin'. The locations of two Indian traders are shown: 'J. Letorts Store' at the West Branch fork, and 'John Skulls Store' further south. The map would appear to predate John Harris' ferry at Harrisburg.
	1728.1 THE ENGLISH EMPIRE IN AMERICA BY R B, from a reprint of the 1685 edition of Nathaniel Crouch's book of the same name (McCorkle #728.1).
	1728.2 A CHART OF THE ATLANTICK OCEAN FROM BUTTONS ISLAND TO PORT ROYALL, by Nathaniel Cutler & Edmund Halley, London 1728. This map shows the east coast from Labrador to Carolina. A large inset map of the Chesapeake and Delaware Bay area names 'Pensilvania.' The map is from Atlas Maritimus et Commercialis, published in London in 1728 as a competitor to the English Pilot. The map is #728.2 in McCorkle, where John Senex is identified as the possible maker. Edmund Halley is otherwise famous for the comet named after him, and for cajoling Isaac Newton into writing the Principia, which Halley published at his own expense.
	1729.1 NOUVELLE HOLLANDE, (A PRESENT NOUVELLE-YORK) NOUVELLE-ANGLETERRE, IT UNE DE LA VIRGINIE..., by Peter van der Aa, from Galerie agreable du monde, vol. 64, Leiden 1729 (McCorkle #729.1). This is another Jansson-Visscher map with a somewhat different title.
	1729.2 NEW ENGLAND, NEW YORK, NEW JERSEY AND PENSILVANIA. by H. Moll geographer, from Moll's Atlas Minor 1729 (McCorkle #729.2). This is called the 'Post Road' map because at bottom right it says "An Account of ye Post of ye Continent of Nth. America...," and it shows the coastal road from north of Boston to Philadelphia. It is larger and differs somewhat from Moll's 1708 map of similar title though the area covered is the same. This map appeared in editions of the Atlas Minor and English histories and McCorkle illustrates several versions. Longitude west from London, blank verso. Scale: 1 inch = 50 miles. Size: 8 x 10.75 inches.
	1729.3 A NEW MAP OF YE NORTH PARTS OF AMERICA CLAIMED BY FRANCE UNDER YE NAMES OF LOUISIANA, MISSISSIPI, CANADA & NEW FRANCE, WITH THE ADJOINING TERRITORIES OF ENGLAND & SPAIN. by H. Moll geographer. 1729. This map (McCorkle #729.3) is from Moll's Atlas Minor and is a reduced version of a world map he published in 1720. There were many subsequent editions of the Atlas and the image here is a circa 1730's version that lacks the date but is otherwise identical. The map is colored to show who controls what; the Spanish own Florida and the southwest, the French part of Canada and Louisiana, the English the eastern United States to the Mississippi. All the colonies are shifted too far north, Pennsylvania lies alongside Lake Ontario. There is a curious defect in the longitude marking which says "east from London" when in fact it is west. Blank verso. Scale: 1 inch = 275 miles. Size: 8 x 10.75 inches.
	1729.4 VIRGINIE, GRANDE REGION DEL 'AMERIQUE SEPTENTRIONALE..., published in La Galerie Agreable du Monde..., A Liede, Pierre Vander Aa, 1729 Vol. 63-64. This map is called state 2 by Verner (in Chapter 4 of Tooley) of the Montanus/Ogilby derivative 8 of John Smith's map of Virginia. The coverage extends north to 41 degrees and so includes a slice of southern Pennsylvania. The state 1 titles and cartouches were removed, the map retitled and some additional place names added. The Dutchman van der Aa was based in Leiden and apparently all (or most) of his atlases were made from outdated plates acquired from other and better cartographers. This map is #229A5 in the Maryland Archives.
