That fits. Sarah Stock, the widow of Joseph Stock died in 1865 and it is then that I understood Bournbrook Hall was sold, presumably to the Martins and then to the Cadburys. I visited and walked through the gardens last August/September. Harriet Stock, daughter of Joseph and Sarah married Robert Smith Bartleet of Redditch. She donated the fountain that to this day features on the Redditch village green.
