The East Window, St. Mary's Lydiard Tregoze, by Brian Carne

A detailed description of the heraldry in the 17th century east window of St. Mary's church which shows the descent of the manor of Lydiard Tregoze from the time of the Norman conquest to the St. John family's arrival at Lydiard Park in the 15th century.

Crests of the major family's are the hares of Tregoz, the golden eagle of the Grandisons, the falcon of the St. Johns and the monkey of the de Ports.

The article points to inconsistencies in the heraldry and explains their potential cause. The origin of the St .John family falcon is also described.
