My sister found Anna "Chippie" (daughter of William E. Chippy and Frances Cavendish) on the 1880 census with Mary Jane "McClurg" (maiden name Hughes, widow of John Cavendish). Anna is listed as Mary Jane's granddaughter.

We had been looking for Anna to be living with a relative since she is not on any of the censuses with her father and his wife, Lucinda Ealy.

We'll still look for a birth certificate or other information, but this seems to confirm that Anna Chippy was in fact the daughter of Frances Cavendish, daughter of John and Mary Jane.
