"John [Knightley]...draws upward the fortunes of this younger house of Knightley [and] marries an heiress, Elizabeth, daughter of Adam of Burgh and granddaughter and heir of William of Burgh by his wife the heir of Cowley of Cowley, and by this match came Burgh Hall and Cowley to the family of Knightley. ...For the line of Knightley we turn to [John Knightley's oldest son] Richard of Gnosall [in Staffordshire, England], who adds Fawsley [in Northamptonshire, England] to his Staffordshire manors of Burgh Hall and Cowley and dies in 1443, first founder of the long line of Knightley of Fawsley.
"The year 1416 was a marked epoch in the history of the Knightley family, since it was at that date that they acquired the manor of Fawsley, which from that day to this has been their home. In the picturesque little church, which lies at a short distance east of the manor house, generation after generation have found their resting-place, and a careful study of the monuments it contains reveals much family history. But, as is the case in most families, one or two only in each century are sufficiently remarkable to deserve a record in the pages of the county history.
"The purchaser of Fawsley was Richard Knightley of Burgh Hall, in the county of Stafford, and the first of the family to represent the county of Northampton in Parliament. He died in 1443, leaving his wife Elizabeth Purefoy in possession of the property, so that their son, also Richard Knightley, only succeeded to the estate on her death in 1474. He married Eleanor daughter of John Throgmorton of Coughton, having been knighted in 1494, when Henry VII.'s second son, afterwards Henry VIII, was made Duke of York. He was three times sheriff. They had nine children, of whom the eldest, Richard Knightley, married Joan Skenard or Skimerton, daughter and heir of Henry Skenard of Alderton. She brought in a great number of the quarterings which are still included in the Knightley shield. The fine altar tomb in Fawsley Church is erected to the memory of this lady and her husband. He died in 1534, but apparently the monument was erected in her lifetime, as no one has ever taken the trouble to fill in the date of her death. Her only daughter Susan married Sir William Spencer of Althorp...."
