1911 4 Summerville Terrace
Joseph Charles Green , 51
Ellen Louisa hill 52
Ellen hill 73, widow , wifes mother
John robert Hill age 40 , married, visitor
George victor Hill 13 visitor
Johns wife Alice and daughter Rhoda May age 4 are at a different address in 1911
but all the family John , Alice , George and Rhoda are at Heath cottage , Doddenham in 1921.
John married Alice Griffiths in 1897 and Joseph Charles Green was a witness
If it is the Hill family you are interested in , I have found an entry of John Robert Hill of Doddenham wife Alice, in RAF entry in 1918
if this is when he left the service it probably meant that he flew for the Royal Air Corps in WW1.
