Hello Jan, I note your post was some time ago, so not sure if my input is still relevant to you.
You mention your relative Jones, living at Ballingdon Grove 1860. However I can confirm my Family lived at the Grove from late 1700's at least until 1911 when the last record I have of Elliston Allen living there until he died. They owned the Brick works and Malting's at the Grove, their time there is quite well documented. It may be that your relatives lived at one of the surrounding buildings, ie Grove cottage, or maybe Ballingdon Hall. I'll look out for records of Jones in the area and let you know if I stumble onto anything.
