I believe that the 7 July 1824 date is off by one month and should be 7 July 1824. His military records (including original application for tombstone available on Ancestry ) and his contemporaneous obituaries indicate a 7 June 1824 birthday. July 7th seems to have been a recent addition to his biography.
