My great Grandfather, William Thomas Thompson, Born 25/04/1852 Goudhurst Kent (Birth certificate held). Married 13/12/1874 Ivyhurch Kent to Emily Foord (Marriage certificate held). Buried 06/01/1876 Brenzett Kent age 23 (Parish register entry No 321 Page 41 copy held). I am unable to find a GRO reference in order to get a death certificate. I wish to find out the cause of death at such a young age.
