I was quite young when I regularly met uncle Randolph. He and auntie Doris (not certain of her maiden name,) lived in Matlock Bath. My mother, Dorothy, adored her brothers. She often spoke of Wilmott who must have died in the 50s or earlier and we regularly visited Randolph.
However, I have little knowledge of their father, Randolph, about whom the subject of this thread was started, other than that which you already have save for my mother stating that he was a tall kindly man who worked hard to keep his family but died of a heart condition manifested by moving railway track sleepers too often - which seems incongruous with his job as porter. It may be that his duties were more general on the line through Matlock, Darley Dale, Rowsley and Bakewell, but I always thought it strange. Whether there was another reason, I do not know. Nevertheless, my mother remembered them with a sincere fondness.
