John and Hannah Standiford lived in Nicholas County in the Lower Blue Licks area for the rest of their lives. They are in the 1850,60,70 & 80 census. Hannah is in the 1900 and 1910 census living with her youngest son, Clark (Ray Clark) and his family. She is a widow so John died between 1880 and 1900. Here is the info I have on Hannah:
