"Near Spillimacheen Landing Captain Armstrong pointed out to us a fine snow-peak to the west named by him, in 1886, Mount Ethelbert....." (Across the Purcell Range of British Columbia, by T.G. Longstaff, reprinted in Canadian Alpine Journal vol III, 1911, p.30.)
"Named in 1886 by Capt. Armstrong, for a nun who died on his vessel, the Ptarmigan." (The Purcell Range by Dr. J.M. Thorington, published by the American Alpine Club 1946, p.32.)

"This is named after the first nun to ascend the upper Columbia River. She died aboard Captain Armstrong's river boat, the Ptarmigan, and was buried as Sister Ethelbert (a surprising name for a nun--one wonders if Armstrong got it wrong). In any event, Armstrong named the mountain after her."
