William Fisher was killed in a riding accident when John was 15. John's relationship with his mother Sophie suffered from their separation, and he never saw her again. However, he continued to send her an allowance until her death. In 1870, she suggested visiting Fisher in England, but he dissuaded her as strongly as he could. Fisher wrote to his wife: "I hate the very thought of it and really, I don't want to see her. I don't see why I should as I haven't the slightest recollection of her."
