After Cooper's death, his widow, Annie Cooper, donated £600 to Bulwell St Mary's for a better organ. Still in use, though now electrified, the organ houses a plaque marking her donation in memory of her husband. Some sources claim this was the same S. T. Cooper who later enclosed Bulwell Bogs as his own private ground. It is known that Cooper died in 1871, aged 39, and that the protest over the Bogs took place in 1872, but this does not preclude a protest taking place after his death for actions made whilst still alive. There is no other S. T. Cooper recorded as lord of the manor of Bulwell.
