I too have Chaney's from Pike County, Kentucky. My ggggrandfather was also a John Chaney. I have not been able to find who his parents were. My John married Elizabeth Blair. They had at least 8 children, although between the cousins I have found, we can only honestly name 2 sons....Jacob and William Preston. Census records confirm 4 daughters and 2 more sons which we haven't been able to find.
My ancestors left Pike County around May 1864 and settled in Meeker County, Minnesota for a time. Most of the family traveled on to the state of Washington, while my ggrandparents traveled south to Missouri.

so we can possibly compare notes.
