The Cronyn Memorial Window was dedicated on October 9, 1949. It was donated by Dorothy Cronyn in memory of her husband Richard Hume Cronyn who trained soldiers in Canada for the First World War and their son Flight Lieutenant Peter Hume Cronyn, who died during his service in the Second World War.
The window was created by Robert McCausland Limited, Toronto. This three-panel window depicts a large figure of the Resurrected Christ in the center window. Flanking symmetrical lights consist of a large number of angels with two large angels holding the scriptures (one in each window). Christ's image in the center conforms to early modern troupes where Christ is framed by a mandorla and ascending from a closed tomb upon which two guards rest. The closed tomb and sleeping soldiers enhances the miracle of the event.
The church was originally called The Memorial Church and officially opened on December 14, 1873. It was the gift of the Cronyn family in memory of their father Benjamin Cronyn who became the first bishop of the newly created Diocese of Huron in 1857. Bishop Benjamin Cronyn is Flight Lieutenant Peter Hume Cronyn’s great-great-grandfather.
