Lewis Evans (surveyor)

[2] As a surveyor, Evans traveled in the Onondaga country of the Iroquois in western New York province with Conrad Weiser, an important interpreter who had lived as a youth with the Mohawk, and botanist John Bartram.

[2] In his A General Map of the Middle British Colonies in America (1755), Evans expanded his reach to include Pennsylvania, Virginia, Maryland, and part of New England.

He had met Benjamin Franklin and helped finance publication of the map by Evans, as both men considered it critical during the French and Indian War.

Evans's map was highly regarded and used by General Edward Braddock during the war; Pownall received most of the public acclaim for it at the time.

His body was returned to Philadelphia, where he was buried in the noted Christ Church Burial Ground, now listed on the National Register of Historic Places.

They had five children together, among them their daughter Anna Africana Barry, who married a Swiss merchant in Livorno named Rodolfo Schintz.

The widow Amelia Evans Barry anonymously published a novel, Memoirs of Maria, a Persian Slave (1790), financed by subscription.

Evans's General Map of the Middle British Colonies in America , published in 1755, was made in collaboration with Thomas Pownall , to whom Evans dedicated it.
