It could be possible with the absence of the father for the family in "The Slope"- that he (the father)could have been a collier of the Princess Royal Pits.

The son, William (my great-grandfather), was a deputy collier when he was killed in Nov. 18, 1936 (58 yrs) in a mining accident. My great uncle William Hill also worked at Princess Royal but quit soon after the death of his father.
