In 1898 she married Charles William Nettleton (1871–1962)[2] and during the Great War she was a certified mechanic in the Motor Section of the WVR.
[6] Her greatest alpine achievement during those years was leading the traverse of the Aiguille du Grépon in 1903, accompanied by her husband and a porter.
One of those was Kern Knotts Crack on Great Gable in the Lake District, about which George Abraham wrote "an expert, and none other should attempt the course"[7] in the introduction to his book he adds that "The traverse of the Aiguille de Grepon at Chamonix is just as much rock-gymnastics as the ascent of Kern Knotts Crack on Great Gable".
She led Kern Knotts Crack at the age of 23, only a year after Owen Glynne Jones had made the first ascent in 1897.
In 1933, 1939 and 1946 she was the British National Champion[9] and at the 1939 World Archery Championships she was awarded the bronze medal in the women's individual competition.
