She modelled for Annabel Lee y079 in the summer of 1871.
Nothing is known about her family except that she had a brother. Whistler's mother, Anna Whistler, described the unfortunate end of her modelling career:
'A lovely study ordered two years ago by a wealthy M P. was promised in August. A beautiful young girl of 15 had posed for it, she was a novice & soon wearied standing & pleaded illness, then her brother in play with her as she was at home hurt her seriously & she had convulsions. poor Jemie does not relieve his trouble by talking of it, but I saw his misery. ... if the youthful Maggie had not failed Jemie as a model for "The girl in blue on the sea shore["] which I trust he may yet finish for Mr. Grahame, he would have had no time for my Portrait...'A.M. Whistler to C.J. Palmer, 3-4 November 1871, GUW #10071.
Instead Whistler painted Arrangement in Grey and Black: Portrait of the Painter's Mother y101.
