Would be good to try and track down his first name, hard one to search for as google thinks you're talking about Alex Honnold 🤦♂️ Might be some clues in climbers club journals from the time.
Sansom's 1914 FRCC journal description of the first ascent refers to all climbers only by their surnames. One wouldn't want to get too personal! https://www.frcc.co.uk/wp-content/uploads/simple-file-list/Journals/Journal-1914.pdf
I shall continue digging.
