I also have this WIlliam C. as a son of Lewis H. Mattingly and Margaret Watkins. It's worthwhile pointing out that according to all the census records, this William C. was born about 1826; 19 years younger than the one that married Teresa Irene Girten. The 1860 census also shows a brother named Daniel living with this William C. and his wife Elizabeth. >I also have a William C. Mattingly of McLean County, KY but I have him as >the son of Lewis H.
