Ann Pouder claimed to have been born on 7 May 1807 in London, UK. She was originally allegedly validated by Alexander Graham Bell, and accepted by the GRG as born on 8 April 1807. Ann died on 10 July 1917 in Baltimore, USA at the claimed aged of 110. However our work has concluded that she was in fact born on 3 May 1808 instead, which would have made her "only" 109 years and 68 days.

Of course, she still would have been one of the oldest people to have ever lived at that point in time - and this should not be forgotten. She can be considered to be validated at the age of 109. Her date of birth was prior to civil registration in England, so it is understandable that she might not have recalled her date of birth with great accuracy, and I believe any error was accidental. She was consistent about her claimed date of birth for many years.
