Leila Ida Nerissa Bathurst Waddell, also known as Laylah, (10 August 1880 – 13 September 1932) was a violinist, daughter of Irish immigrants to Australia, David Waddell of Bathurst and Randwick.
She became a famed Scarlet Woman of Aleister Crowley, and a powerful historical figure in magick and Thelema in her own right.
While Creswell states Leila was part-Maori, he provides no evidence of this; in fact NSW birth deaths and marriages records show she was the granddaughter of John Crane (Coventry) and Janet McKenzie (Fort William Inverness) and John Waddell (Monaghan) and Elizabeth McAnally (Monaghan).
