The 1901 and 1911 census pages for the Grahams not only have scans of the handwritten forms (and I think John Graham filled out the 1901 form himself, because the handwriting matches his signature), but scans of other forms, including a record of who was in the shops along Greencastle street, and the number of rooms.
In 1901, the Grahams are shown at number 4, living in 6 rooms.
In 1911, number 4 is blank (a row of dashes), and John Graham and his boot shop are shown at number 61, with 11 people staying in 6 rooms (however, two of them, Herbert Buckley and Walter Balson, are visiting grandsons of Annie and Bessie, who are married and living elsewhere). The family census form confirms this, showing the street number 61. So it seems that the boot shop may have moved between about 1907 (the date of the photo in an earlier post above) and 1911.
And I have found another photo, showing Bessie and her family with a couple of Bessie's sisters, I'm guessing in the early 1920's judging by the age of the young boy at bottom right (my father), born in 1917. Bessie is on the right, and two of her sisters are on the left, named as Aunt "Gorly" and Aunt Maud respectively, by Bessie's daughter Olive (standing next to her mother), who labelled this photo.
