According to the reference quoted below, 'it is said that Nettlestead church owes its enormous stained glass windows to a 15th-century Agincourt veteran who came back from France very impressed with what had already been done with stained glass decoration for churches there.
The man was Reginald de Pympe, and his son, John, added more stained glass later in the same century. The de Pympes made quite an impression upon Nettlestead in their day. Reginald moved into Nettlestead Place, which he rebuilt at about the same time as he had the church rebuilt and embellished with the new glass.
