CWGC Headstone, Northfleet Cemetery

Looking for a specific CWGC headstone - A Hammond; the relevant stone was found quite by accident. The enveloping brambles, thorns, weeds, ivy and vegetation was removed to reveal not alone the headstone but also commemorative memorials to two of his sons - one killed in action in World War 1, the other killed in action in World War 2.
One wonders on the words 'they shall not be forgotten'.....
