First wife of Joseph Andrew Morgan. I think her first name was Nezzie?

Her first name was Nezzie. She was my grandfathers (Joseph Andrew Morgan) first wife. She died from malaria fever shortly after giving birth to their second son. She is buried in Redfield, CA with a baby boy. I believe that she was born somewhere around Bay,Dell, or Lakecity, AR.

Does anyone know this girls last name or any information about her?
