Scotty,
Have you located the family in the census records? If not this could possibly be your family in 1891
46 Isles Street, Manningham, Bradford
William D Walker age 55 Excavtor? born Northowram, Yorkshire
Ellen Walker age50 born Cork, Ireland, Wallstown
John Walker age 20 Masons Labourer born Coventry, Warwickshire
Harriet A Walker age 14 born Waterford, Ireland
Michael P Walker age 9 born Liverpool, Lancashire
I could look for them in other census records if it would be of any help.
