John Valentine Akers and Hannah Blankenship~Marriage
The 08 July 1847 date for the marriage of John Valentine to Hannah Blankenship is found in many sources. I will cite here the Roots Web Floyd County Kentucky website.
Kathy Hamilton has a page there listing the Pike County Kentucky Marriages for 1818 to 1875. I've contacted Kathy and asked for the actual sources and will publish those here when I have them.
In the meantime, you may access Kathy's list of those marriages Here
