Don't know if this help but I also have a Laughton that would have been in the London area at the same time but have not checked the 1881 Census yet.
David Laughton b 14 Aug 1856 Southend, Argyleshire, Scotland married Clara Harriett Norton in 1875 in London and imigrated to Australia in 1883.
It is part of Family History that the actor Charles Laughton was a cousin.He was born 1st July 1899 and died in 1962 He was the son of Robert & Eliza Laughton nee Coulon. He had brothers Tom and Frank and a sister Eliza they were born in Scarsborough North Yorkshire.
David Laughtons parents were James & Jane (fyfe) and I only know of 3 children David 1856, William 1862 and Jemima 1866.I would think there would be other children but can not find them as yet.
