Hi Sarah, My Dad was Rev.C.N. Vermillion (1913-1993) The William Washburn and Abby Vermillion that you are speaking of ,I think, may be buried at the "Hillsdale Cemetary" in Bracken Co., KY.I know Elias, and Hezekiah Vermillion are. There is a Washburn Family plot there with an iron fence around it, Beside Hezekiah Vermillion's grave. Also I remember my Dad speaking of "Hezekiah Washburn"Nazerene Missionary to Africa,who was named for his Grandfather, first missionary to the Congo that wasn't eatin', was the story I was told. Are you familiar with Bracken Co. ? The cemetary is on Hillsdale Rd., which runs between Asbury Pike and Rt.#10.
