Chaucer gets there first
The form turns up early in English. Chaucer used the spelling Emelye in The Knight's Tale, a poem the University of Oxford's English faculty describes as based on the Teseida by Boccaccio. His Emily is a prisoner of war taken by Theseus, roaming an enclosed garden while Palamon and Arcite fight over her.
