There is a Robert Roberts born 1864 at 31 Madoc Street in 1871, Mother Ellen and Father Robert. (Joiner)In 1881 R.Owen Roberts is living in The Cottage Back of 31 Madoc Street with father Robert and Mother Ellenor, so looks like the same family, in the later entry ther are younger siblings, George, Louisa J and Rowland E, in the earlier entry there are older siblings Rowland, William,Evan, Thomas and John, with John, George and Robert appearing in both entries. Robert seniors occupation looks unclear but to me appears to read "No Occ" No mention of Prescot House,
