Arthur Knapp Oliver was my great, great grandfather. He was a Bombay High Court judge and married to Ellen Elizabeth Wollaston who was a wonderful water-colourist. I have three of her paintings, one of which was of a Sherpa guide whom she painted when accompanying Mallory - I think - on his Everest expedition. She was painting for the geographical society, my mother thought. She was quite old at the time. They had at least two sons, Cyril and Eric. Eric became a civil engineer and helped design and build the Kuala Lumpur irrigation system before taking up rubber planting in Malaya. He was a well-known tennis player and local regional champion. He won literally hundreds of silver trophies and cups. Cyril remained in India and worked for the Calcutta railway. (I have a report he wrote in 1903. Or maybe, 1913.) I don't have much information to hand as I am not at home.
After Arthur and Ellen retired, they lived on a houseboat in Kashmir until his death, upon which Ellen moved to Malaya to join her son and help look after my mother whose own mother had died of the Spanish flu shortly after giving birth. My mother only recently died at age 97.
PS I have his marriage certificate, if that helps? He had several witnesses, so some names may be familiar.
PPS, Arthur was also a very good tennis player and won many competitions in India and my daughter has a wonderful embossed silver fruit bowl given her by my mother on which Arthur Knapp Oliver's name is written plus other information.
