Mrs Oliver's grandmother Alice Nicholson survived at Wilkinson's. She was saved because a door fell on her and sheltered her from the falling masonry. She was showered with money from a till from the factory which fell on her lap.
Her mother used the shelter regularly and apparently people were in the habit of booking a seat for the shelter if you went in the day time. Her grandfather, William Nicholson was an accordion player. Was he the often mentioned musician at Wilkinson's?
