The glass, now comprising a three-light Crucifixion between two royal figures and their patron saints, reflects the style of Leiden and can be dated c. 1515-27. It may have stood originally in three linked windows in Waltham Abbey Church, and been padded out after the Dissolution to fit the five-light window of the chapel of New Hall, Boreham. On its transfer to Copt Hall c. 1740 William Price the younger replaced some of the glass, and must have overpainted and refired most of the rest. A local glazier, James Loton, was responsible for transferring it to St. Margaret's in 1758.
