HeywoodMary, not Alice, Pemberton.I haven't accessed census 1921 (nor 1911) successfully as yet.Thanks for replying.
Doesn't help with the shop, however Alice Street appears on this 1908 map (top near the middle), off Richard Moon St. It appears to become West Ave on the other side of Samuel St.https://maps.nls.uk/view/114585193
Still no success with 1921 census mentions of Thomas and Mary Pemberton
