William Alexander, who served as secretary to William Shirley during the 7
Years War, drew a map of the area from the Ohio Valley to the Hudson
showing British fortifications in 1756.  It's reproduced in Lloyd A.
Brown, Early Maps of the Ohio Valley (1959).  A map with the same title
(but not identified as being by William Alexander) is listed in the NYPL's
Map Division as being in "Crown coll. of photogr. of American maps,
Cleveland, 1906."  Also in the NYPL is a nineteenth century lithograph of
"Topographical Map of the Country between the Mohawk River and Wood Creek.
From an Actual Survey taken in November 1758" with the original listed as
being in the NY State Library.  Such landmarks as forts (new and old),
carrying places, etc., are marked on the map.  In the NY Historical
Society is a manuscript map labeled "A Map of the Country between Albany
and Oswego," a lovely undated route map (but the Society dates as circa
1756, which seems right) which shows forts, paths, rapids, and
settlements, both Iroquois and settler.

Hope one of these will be helpful!
