Hi,
My late mother-in-law was Antonia Ivy Boxall; the family lived in King William's Town, South Africa. I am not sure of the father's name, but there were three daughters - Antonia Ivy, Doris and Edith. The only connection to the U.K. I have is a story about a Boxall relative who played the violin at a command performance for Queen Victoria in London; his violin was a Stradivarius (it turned out to be a fake when we took it to Sothebys!) - this violin was later donated to a museum in East London, South Africa.
I have not looked in to how they came to be in South Africa; I think they must have migrated sometime during the 1850's or later. I do know that the father married a lady of German descent, one of the many German settlers who came to this area of South Africa at that time.
Ivy Antonia married Ronald Nettleton Gordon and they had two children, Raymond Garth and Margaret.
Cheers,
Tisy
