Sophia Kincaid is buried in Forest Hill Cemetery in Morganton. If you have access to the Burke County Genealogical Society published cemetery volumes, see Volume III, page 11. The information recorded on Sophia's gravestone is that she was born in 1824 and died in 1894. Her second husband Milton Wilburn Kincaid and his first wife Mary Abigail Bristol are buried in a private Kincaid cemetery in Burke County.
You may be interested in knowing what I found on page 13 of Volume III: "Nina Todd, Died 2-14-1880, Age about 24 years, wife of J.L. Todd". Is this the first wife of James Lee Todd? Unfortunately, there is no maiden name given or hinted at.
