‘While this sordid and trivial collection of of evidence slowly piled up at the Prime Minister’s house in Downing Street, the Princess was forbidden to see her daughter. Charlotte, now ten, had already before the Investigation, been debarred from playing with Willikin; and though she can hardly have minded, or at the time have known why, she must have had some idea of what was going on. Her acceptance of the situation, when it came, was clear-eyed, for in 1815 she told the Prince Regent and her aunt, Princess Mary, as if she had always known it, that Captain Manby was the father of William Astin, and that Edwardina Kent, the Princess’s “foundling” daughter, was her child by Sir Sidney Smith. She seems to have had no doubt.
The Inquiry, however, after careful consideration of all the statements, found that there was no proof of the Princess Caroline’s guilt. William Austin was, as she claimed, the son of a dock labourer, and the child’s mother, Sophia Austin, had appeared at Downing Street to confirm this. The Commissioners reported to the King that from the evidence there was no foundation for believing the Princess to have given birth to an illegitimate child in 1802. Nevertheless, they continued, other particulars respecting the conduct of Her Royal Highness “must, especially considering her exalted rank and station, necessairly give rise to very unfavourable interpretations”.’
