Aside from the boys who died in the Wars, I think mine has to be my grandma's sister Jean Mary Nash.
The family lived in Bristol, and the family won some money illegally on a sweepstake or something similar. With the winnings they moved to much more upmarket house in Fulham.
Jean was out one day riding her bicycle when she got hit and killed by a motor car which was driven by an 'intoxicated' driver. She was 15 years old.
It was in the mid 1930's and deaths like that were not as common in those days. People wrote to her parents from as far afield as Australia and New Zealand to sympathise with their loss. My great uncle still has all the letters and cards, there is a whole suitcase full!
Her parents believed that they had been punished for the illeal gambling, sold up their big house and moved down to Portsmouth. They never actually told my grandmother that her sister had died, and never spoke about her.
