Brosdale is not mentioned by name although there is a laconic entry referring to a Hasil Iyle "which in the Erish is callit Ellan-na-Crawiche".

R. W. Munro was unable to identify the location of Hasil Iyle but writing 40 years later Peter Youngson suggested that Monro was referring to Brosdale.

[4] Matheson, as evidence for his idea that Brosdale is Ellan charn, states that it "appears on an old map as Chreig Yl.?

"[6] and mentions that the modern name has "obviously been re-named after Brosdale on the mainland of Jura opposite".
