[2][3] They were the two eldest of four sons of George Perry Abraham (1844–1923), a photographer, postcard publisher, and mountaineer, and his wife Mary Dixon.
[4] One of their many first ascents in the Lakes was the 74 m "Keswick Brothers' Climb" on Scafell crag on 12 July 1897, now considered "Very Difficult" in the British grading system.
Another memorable first ascent was of "Crowberry Ridge Direct" (graded "Severe") on the Scottish Munro Buachaille Etive Mor in 1900.
[3] Many of their climbing photographs, (including the classic portrait of Owen Glynne Jones), were reproduced in Alan Hankinson's Camera on the Crags.
A large selection is also in the possession of the FRCC (The Fell and Rock Climbing Club of the English Lake District), of which the brothers were founding members and Ashley its first president.
