There's a picture of Sir Ernest at

1. According to

Sir Ernest Oppenheimer also had a brother, Louis Oppenheimer.

2. The children of Harry Frederick Oppenheimer

See Mary Slack and Nicky Oppenheimer

3. Nicky = Nicholas Frank Oppenheimer Wife Strilli (daughter of Helli Lasch) Son Jonathan

Emmanuel (Mannie) Jacobson, a gold prospector, was involved in the discovery of gold in the Orange Free State on a farm known as Aandenk. A monument has been erected by the Historical Commission on this site as a mark of the first borehole and names those individuals that were involved in mining gold at Aandenk. (Unfortunately my father and his partner ran out of money with only 400 feet short of reaching payable gold!). Ernest was approached to invest in their company Wit Extensions as it was called, and the borehole was taken over by Anglo American (Oppenheimers) in 1945.

Mannie and Ernest Oppenheimer are both featured in two books: The Historical Monuments of South Africa and the Gold Miners of South Africa, the latter giving the history of the gold miners from 1885 - 1961. Harry Oppenheimer is also featured, however to a lesser extent.

Sir Ernest's first wife, Mary, died about twenty years ago: he is now married to the widow of his nephew, who was the son of his brother Bernard. The nephew was named Sir Michael Oppenheimer, so Sir Ernest's wife, who was Miss Caroline Harvey, has been Lady Oppenheimer twice. The fact that her son by her first husband is in his turn Sir Michael Oppenheimer, and that his wife is thus also Lady Oppenheimer, doesn't make matters any easier for a newcomer to the Oppenheimer family circle. describes re Ernest:

His first wife, May Pollack, with whom he had two sons, died in 1934, and his son Frank died after a swimming accident in Madeira in 1935. Ernest underwent a spiritual crisis because of these losses, and converted to Christianity that year. A few months later, he wed Caroline "Ina" Harvey, daughter of an English baron and widow of his nephew Michael, who had died in a 1933 plane crash.

Sir Bernard's daughter married a Mostyn Owen



There are some definite matches there - in particular Arthur and Charles and Roger.
