If this photo is from 1911 then, according to the census, it seems that the people in the picture maybe Joseph and Rebecca Flack, both aged 69. Joseph was formerly a cowman and they had been married 43 years and had 12 children, 8 of whom were still living at the time of the census. 10 years earlier in 1901 they were living in the same cottage with 3 children still at home, Herbert, Matilda, and Frank.
