I have not found her on the 1939 register yet - various names she could have used.

Mary Elizabeth Hands possible death in 1963 in Maidenhead, Berkshire under the name Mary E SUGDEN.?

**Death of Francis Hand "Blyth News" 13th May 1898.
FATAL ACCIDENT AT CROFTON MILL PIT. Was anyone to Blame?
The victim was a man called Frank Hand of Cowpen Quay. There had been a fall of coal and stone and this had caught Hand about the head and shoulders, killing him almost instantly. The deceased who leaves a widow and four children had only been employed a short while at the mill pit. William Lazenby, miner, living at 17 Coburg St. Blyth said the deceased was his brother in law, and was 39 years of age and a miner living at 98 Hambledon St, Cowpen Quay. He was employed at the pit as a stoneman. John Richardson a putter lad said he was working with Hand packing stones. At about ten past midnight the deceased was packing a pillar close to the 'face' when the fall occured. Richardson saw Hand on his hands and knees unable to speak but he lived about 5 minutes after the accident. His head was seriously injured at the back and witnesses thought his neck was dislocated. A witness said as far as he could see there had been a stone overhanging the face of coal and it had fallen away onto Hand who apparently had been stooping. It was all stone that was on the deceased. The overhanging stone in his opinion should have been taken down; the stone was about 7ft long, 17ins broad and 16ins thick. A chargeman said he had just examined the place Hand was situated and thought it to be safe. The manager of the colliery said the stonemen had no right to take 'the ramble' down, this should have been done by the hewers. (There were also discussions that the hewers had not been doing their job of clearing away such 'ramble') Eventually the jury found that the fatality was down to accident and natural causes and that there was no blame attached to anyone.
