Accidents or more sacrificed sons?

Since creating my first post on this subject, I have become aware of many more examples of untimely deaths of sons, toxic legacies and parents who outlive their children.

Alexander Mosley, the elder son of Formula One chief Max Mosley, was found dead in 2009. A drugs overdose - accidental or deliberate - was discovered to be the cause. Alexander Mosley was said to be a maths genius and a fragile person. He inherited the poisonous legacy of British Fascism and had a notorious father and grandfather.

L. Ron Hubbard’s oldest son Quentin died at the age of 22 after being found in a coma in his car. His death is believed to be suicide. He inherited the poisonous legacy of Scientology and had a notorious father.

Robert Maxwell, the notorious media tycoon, died mysteriously. One of his sons died tragically:

 “…his eldest son, Michael, was severely injured in 1961 (at the age of 15), after being driven home from a post-Christmas party when his driver fell asleep at the wheel. Michael never regained consciousness and died seven years later." 
- From Wiki.

J. M. Barrie had no children of his own, but befriended and informally adopted the five Llewelyn Davies boys. He outlived two of them: the oldest son was killed in action at the age of 22, the other drowned in what may have been a suicide pact when he was 21. Of the remaining three, one committed suicide when he was 63. 

Mark Twain outlived three of his four children. His only son died of diphtheria when still a baby.

Unseen Influences: the sacrifice of the sons?

When I was very young, I was an avid reader of the works of such prolific novelists as Sir Henry Rider Haggard, Rudyard Kipling, Sir Arthur Conan Doyle and Rafael Sabatini. I knew at the time that both Rider Haggard and Kipling had a son who died young; it wasn’t until many years later that I learned about similar tragedies in the lives of Conan Doyle and Sabatini. 

Rider Haggard’s only son died of measles around the age of ten. 

Rudyard Kipling’s only son was killed in the first World War at the age of 18. Rudyard Kipling had lobbied for his son’s conscription after the boy was declared unfit for military service. Sadly, Kipling’s elder daughter had earlier died of pneumonia at the age of seven.

Conan Doyle’s first-born son died at the age of 25 in the flu epidemic in 1918. 

Rafael Sabatini’s son and only child died in a car accident at the age of 17 or so. Mrs Sabatini was in the car too but survived: she was thrown from the car, which reminds me of the fatal car accident involving Monaco's Princess Grace and Princess Stephanie. Rafael Sabatini’s young stepson died in a plane accident after joining the RAF. Something went wrong when he flew over the family home to demonstrate his new skills, and his plane crashed in flames nearby.
