I am looking for information and a marriage certificate for James Riley Blankenship 1817-1865 and Nancy Lark 1827-1901. My grandmother told me Nancy's maiden name was Lark (Riley & Nancy were her gggrandparents) as told to her by their son William Alex Blankenship. I have seen some family lines showing her parents as Blankenships. I have 4 death certificates of her children that list her maiden name as Lark. My grandmother was like a vault when it came to family lines. Does anyone have proof that would confirm or disprove she was a Lark?
