On October 8, 1879, Nannie Honshell married State Senator
Lindsey Kelly, the son of a
pig iron magnate. Lindsey Kelly was the owner/manager of Center Furnace, a
charcoal iron furnace in
Lawrence County, OH. When he died in 1902 (as did their one child, Lindsey Kelly Jr.), Nannie Kelly became sole proprietress of Center Furnace. She managed the furnace personally and travelled to Cincinnati weekly to work to sustain the profitability of the furnace. She also inherited from Lindsey Kelly the directorship of the Kelly Nail and Iron Company of
Ironton, OH. As the iron ore industry began to decline, the
Ohio State Journal noted that Mrs. Kelly "lived in the furnace region, in a primitive house; mined ore and limestone, endured a hard and rugged life, but ever bright, buoyant and full of social engagement with old friends, she lived in the constant hope of retrieving her fortune." Rumor had it at the time that she sometimes worked the furnaces in male clothing, but she always steadfastly denied this. In the end, she was successful at regaining her fortune, and shortly after the turn of the century, she was thought to be the richest woman in the world after
Queen Victoria. ==Second marriage and sale of Center Furnace==
