I believe this may be the gravestone of my 6x Great Grandparents! I am definitely descended from Richard Bull and Jane Wyatt who were from Fawley in Hampshire and married around the year 1800. These are perhaps the parents of Richard Bull, who I believe was born around 1768 (he is aged 70 on his 1838 death certificate).
