Steve Rankin sent me an interesting article about female map makers of the 19th century. It reminded me of an additional local example: Lucy Worth Jackson. Ms. Jackson's husband was a miner, or maybe more like mineral speculator, who owned a coal mine near Carbonton in Chatham County and also a "gold mine" on Cane creek in what is now Alamance County, then considered Chatham.
Ms. Jackson made at least two beautiful color maps of areas in Chatham County:
Map of the Coalfields of Chatham and a Portion of the Mineral Region of N. C., circa 1874
Map of Cane Creek Gold Mines, Chatham County, North Carolina, circa 1878
Copies of the first map above can be purchased inexpensively from http://chathamhistory.org/publications.html
The second map is posted on the NC Maps site: http://dc.lib.unc.edu/cdm4/item_viewer.php?CISOROOT=/ncmaps&CISOPTR=2384&CISOBOX=1&REC=6
Lucy Worth Jackson was the daughter of Gov. Jonathan Worth.
