Poland Map: 1799
Entitled 'A New Map of Poland, and the Grand Duchy of Lithuania, Shewing their Dismemberments and Divisions between Austria, Russia, and Prussia, in 1772, 1793 & 1795, from the Latest Authorities', this 1799 map by John Cary shows towns, villages, detached territories, internal "palatinates", as well as the division of Poland in the late 18th century. Covers the area from Poznan in the west to just west of Smolensk in the east and south as far as the Hungary-Moldavia borders. Good detail for the area of Galicia. Black and white map.

Poland Map: 1817
N. R. Hewitt's map of Poland was first issued in London in 1817. Showing Poland divided into its internal "palatinates", the map has rich detail, locating cities, small towns and villages. Because this map contains different cartographic information - and many different village and town names - the researcher will find it a fine companion piece the Poland - 1799 by John Cary. Black and white map.
