From the 1881 census it appears that Alice and her mother were living with Mary A. and her brother William Blake. So in other words, Mary A. Rutter, a widow was the mother-in-law of William Laws, who was the husband of Mary A. - obviously being Mary Ann Blake shown on the 1871 census. In the household was another of Mary A. Rutter's earlier children - William Blake who was working as a bookbinder. Alice Rutter was working as a book folder.
