Later life
The duchess died at her home, Burlington House, Piccadilly, and was buried in St Marylebone Parish Church, Marylebone, London. She “died of a bowel complaint, which she had been subject to for many years, and which terminated in a mortification after a short illness. It was at first suspected, from the violent inflammation in her bowels, that her Grace had eaten water-gruel out of a copper saucepan not properly tinned; but this suspicion is certainly erroneous, as it proved on examination.”Bentinck was a great-great-great-grandmother of Queen Elizabeth II
