She is the daughter of John Simon Masters and Judith Riley of Overton County, Tennessee. She married John Dennis Knox August 19, 1854 in Monroe County, Tennessee.

John and Amanda left Overton County by 1870. Perhaps after the family disagreement listed below. The family has not been found on the 1870 census. A daughter was born in Jonesboro, Illinois in 1874 and the youngest child was born in Ripley County, Missouri in 1876. By 1880 the family the family was in Boone County, Arkansas. Application for homestead was made in Feb 1884 and the John and family moved onto the land in Marion County in 1883. Patent was received in 1890.

Amanda and John moved to Wynnewood, Oklahoma where John worked as a cashier in a bank (this is an inaccurate story as John died in 1893). Amanda moved to Wynnewood before 1900.

It is not clear if he died in Arkansas or soon after arriving in Oklahoma. It does appear John died on his homestead. He is added to Amanda's stone as a memorium.

He is remembered as a large distinguished looking man who was interested in the gold which Amanda’s father John supposedly buried. He and Amanda were opposed to her fathers’ will giving the farm to the three youngest sons and attempted to break the will. (Th there is a court case where John and Amanda contested her father's will. It is also said the couple left Overton County, Tennesse because of hard feelings in the family.)

John and Mandy traveled to Illinois where the second youngest was born in 1874. I have not found them on the 1870 census but they are likely near one of Mandy's siblings that moved to Illinois. John also had cousins from his mother's Dennis family that moved to Illinois. John and Mandy's next stop was Missouri where their youngest daughter was born in 1877. Then on to Boone County, Arkansas by the 1880 census.

John and son Jessie homesteaded in Marion County, Arkansas. It appears the farms failed by 1891.

The next move was to the Oklahoma Indian Territory. From the probate record of son, Robert T, in 1906 John's death is listed as December 18,1893. The record does not say where he died. The first Knox burial in Oak Lawn Cemetery is Jessie's son, John William, at age 3 1/2 on June 12, 1893. The cemetery has no record of John Dennis's death but it is likely he is buried in Oak Lawn Cemetery as the records are very poor at that date. Amanda and most of their children are burien in Oak Lawn Cemetery.

There are no stones for Amanda or John Knox. Daughter, Tennessee, also does not have a stone.
