Hi, John. The Catawba Co NCGenweb site has done of fantastic job of giving us just what we need for the shifting and splitting counties. They have a series of easily printable simple maps ranging from 1700 to the present day, showing the county changes. Rowan county, with no western boundary, first appears on the 1760 map. http://www.rootsweb.com/~nccatawb/countyfm.htm Also, I found another site useful. It gives a listing of counties, their formation dates and parent counties, etc. http://www.goldenbranches.com/nc-state/counties.html Good luck, Linda
