- A stillborn baby, birthed at Burlington House on 20 October 1786.[3]
According to newspaper accounts, she was the mother of nine children, only four of whom were living at the time of her own death.
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.”[4]
Bentinck is a great-great-great-grandmother of Queen Elizabeth II (see ancestry of Elizabeth II)
