Margaret by now you probably have more info about the Cranberry Iron Mine than is needed.I found your message today.If you need more info go on line and find a book named Mines Miners and Minerals of Western North Carolina by Lowell Presnell.It will cost you about $15.00 plus handling.Also you could get your local book store to order it for you.It contains all the names you mentioned.Also if you are researching DUGGER and have information about Presnell college that Monroe Dugger attended in Tenn during I think 1881&82 I would be grateful for that info.Thanks Lowell
