Kate Hunter was my great-grandmother too. She wasn't actually African American. Apparently, she was multi-racial (South Asian (Indian), Cherokee, Irish and French), but not black. She lived with an African American man, though she had her children with the man I think you're referring to as "Wall" Cage. My grandmother (Myrtle) was the only daughter of Kate and William Claiborne Cage. She said he was known as "Captain Willie Cage" though his name was Claiborne. His sister told my aunt Kate Hunter's racial background.
