When Stephen Privett inventoried Gaston High’s estate in 1863, he listed “3 negroes namly Jinsey aged 28 32 years Joseph aged 11 Adaline aged 6 years.”
I don’t know for certain that Jinsey was the mother of Joseph and Adaline, but it’s more likely than not and, even if not, she was surely their surrogate mother.
Nonetheless, on 4 September 1863, Privett sold Jinsey and hired out the two children for $1200.
I have not been able to trace Jinsey, Joseph, or Adaline forward.
