This family can be found laid out here: Edward Ball's family
His grandson, my grandfather, was the Mr Ball of Mrs H.S. Ball's chutney, well known in South Africa.
Please note that the age at death stated for Joanna Thwaites on the inside cover page is almost certainly wrong - presumably one of those family myths that get distorted while being handed down! What I have found of her details can be found here: Joanna Thwaites born Stevenson
