sir robert clayton and his wife, martha, and their son Robert, who had died long before them in his infancy, some say on the very first day of his life

The Clayton Memorial, in the church at Bletchingly, was put up by Sir Robert Clayton very late in his own lifetime, in 1705, in honour of his wife. 

Sir Robert was Lord Mayor of London, Member of Parliament for Blechingley, and a benefactor of St Thomas's Hospital and Christ's Hospital. He lived at Pendell. It is by Richard Crutcher and is considered one of the best examples of the work of that period.  The fine wrought-iron railings are contemporary and were painted blue and gold.

I've photographed the memorial before, but had another chance today when forced to take a "tacho break".
