Thank you for this update. Very sad for the family, especially with a young daughter (mentioned in a New York Times article 2012). He also had two children - Helena Lucia Gore (b. 1993) and John Theodore Gore (b. 1996) - by his first wife Kathryn Ambler [(b. 1966) any relative of John Ambler who married Pss Margaretha of Sweden?] whom he married 1992 in Budapest and divorced 1998.
Updates on the sister: The elder sister Charlotte was first married to a baronet, by whom she had issue 2 children. No children but stepchildren by the 2nd husband. The Duchess of Norfolk is now separated from her husband, per several news report, but still lives at Arundel Castle.
I believe Christopher Gore was twice married, and his 2nd wife was Catherine Maria Dickens (b. 1966), a descendant of Charles Dickens, the great Victorian novelist, whose mother was Hungarian, the former Countess Jeanne-Marie Wenckheim. A young daughter is mentioned in the 2012 New York Times article. She is Maritta Elsa Gore (b. 2004) [

Articles about Mrs Gore
"Among the new residents is Catherine Dickens, the great great great granddaughter of Charles Dickens. Catherine grew up in Yorkshire and, at first sight, seems as English as they come. Yet her mother is Countess Jeanne-Marie Wenckheim-Teleki, from the eastern Hungarian village of Doboz.
The countess lost her parents in the Second World War and fled to London as a teenage refugee. She met and married Christopher Charles Dickens, head of the Dickens dynasty. In the late 1990s, after her husband's death, she returned to Hungary, and her daughter Catherine used to come to visit.
It was on one of these visits, out horse-riding with her mother, that Catherine decided she too wanted to live in Hungary. By that time she was in her thirties, recently divorced after her first marriage had come to grief in the West Indies, and she had no desire to return to Britain. "I am half Hungarian, and this seemed to me a land of opportunity. So I invested in a property here - paying £130,000 in 2001 for a Budapest apartment of 180 square metres." That apartment is now worth £300,000.
Once Catherine had made that decision, her life changed radically. In a corner shop near her apartment in downtown Pest, she met Englishman Christopher Gore, who had arrived in Budapest in the post-1989 euphoria to set up an insurance business. It was Christopher who encouraged her to direct her considerable energy into a business of her own, buying and renovating some of the city's wonderful, high-ceilinged and parquet-floored apartments."
