I have copies of the papers she had on the Evans family and on the front she hand drew a family tree explaining the family. We were fortunate to get these papers from a lovely person that is related to Jonathan Evans also and lives out of Greensville near Warrensburg,TN.
I sent for the Bright Hope Furnace Ledger and a Claude Ferguson was the person I ordered it from back in 1998.His home page at that time was http://ww.kiva.net/~ferguson. His address is 1921 Steven Ave.#660,Bedford,IN. 47421.He may have more info as he said he had some material from Katherine Susong Harmon about 1990.
