The Catesby family had been settled for some time in Northamptonshire and held the manor of Lapworth in Warwickshire.
He became a Serjeant-at-Law in 1463, allowing him to practice in the Court of Common Pleas and a King's Serjeant on 18 April 1469.
[3] He served continuously from the reign of Edward IV to that of Henry VII, although the latter delayed his appointment for a month due to his relation to William Catesby, who had been a close ally of the previous king.
On the death of Richard Neele in 1486 he became Second Justice of the Common Pleas but died later that year.
He married Elizabeth Green, daughter of William Green of Hayes, Middlesex[4] with whom he had seven sons and two daughters; Robert Catesby, the leader of the Gunpowder Plot, was a direct descendant.
