Hi Russel
My name is Lynsey Kriel. My mothers' maiden name is Margaret Clarke. Her mother was Freda Hildegard Wasmuth. I spoke to my mom about your article here. She told me that her grandmother was known only as, "Ma". Johanna died in Groote Schuur (Cape Town) hospital of diabetes. Also, it was her son who was known as Uncle Bertie, and not her brother. Other than that, your article is accurate. I know a few more details about family history, but it's better not to use this platform. One burning question, is your mother Hilary, Jeans' daughter?
