The Longhurst name is not a common one in South Africa. I know of a Claudia Longhurst who was born about 1942 - 1945, probably near Pretoria. Her father was Claude Seaward Bruce Longhurst, in immigrant from England. Her mother's name was Audrey. She had brothers Terence (older) and Graham (younger). Try contacting Helen Longhurst van Wyk (daughter of Terence). Sorry, I have lost her e-mail address, but she may be in the telephone book.
