Josey, I thought this might be the family with William showing like this:
John Inness 44 dairyman b. Tranent
Mary Inness 38 b. Abercrombie, Fifeshire
Andrew Inness 16, son b. Tranent
William Inness 9 son b. Tranent
Address: 82 Bridge St South Side, Tranent East Lothian
Thought this fitted well with what John posted later for 1911:
Address: Bellevue Cottage, Bridge Street, Tranent
John Innes (Head) 53, Married, Dairyman, Employer. Birthplace Haddington, Tranent
Mary Innes (Wife) 47. Years Married: 26, Birthplace: Abercrombie, Fifeshire
William Innes (Adopted Son) 19, Single, Dairyman, Worker, Birthplace: Haddington, Tranent
Georgina White (Neice) 15, General Servant Domestic, Worker, Birthplace: Fife, St Andrews

PS: The only wrinkle is the birth place still of Haddington?
