Descended from a junior branch of the St. John family of Lydiard Tregoze in Wiltshire, St. John’s ancestors had owned property in Hampshire since the thirteenth century.
Later in 1614, St. John leased the Farley Chamberlayne estate to his brother-in-law Sir Richard Worsley* and moved to Norton Walrey following the death of his mother, who had held a life interest in the property.
