Her father was Jan Daniel Goosen who died in 1914 in Queenstown, Cape Province (his father was William Adriaan Goosen born 1798 Graaff Reinet his mother Geertruda E Botma born 1797) and her mother was Elizabeth Jacoba Hendrina Dolfina Lomard who died in 1905 in Queenstown. I have not got their death notices as the South African Archives system has been off line for some time.
