Nancy A. Thompson

I'm looking for info. on Nancy A. Thompson.
She was born in Jackson County around 1835-9.
In 1854 she married John C. Herron.
They had two children, Son Malkiga sp? born 1856, Daughter Martha born 1860.
In the 1860 Jackson County census John and Nancy were living two houses away from Archibald and Martha Thompson, in 1870 Martha is living with John and Nancy.
In 1900, Nancy is living with her son. After that, I don't know what happened to her. She is not buried in Mt. Carmel with her family.
Thanks
Chuck
