"[1] Morgan left Ireland for London in 1824, accompanied by his wife, Bridget, and their infant daughter, Julia.
His motive for this move was to seek a publisher for a poetical work entitled The Wanderings of Lucan and Dinah.
This work postulated the origin of speech in prehistoric "mime" (today we might call it sign language).
For example, Thompson Cooper a near contemporary writing in the Dictionary of National Biography dismissed The Discovery as a "ridiculous work".
[4][5] During this period Morgan submitted several works in competition for the Prix Volney but he was unsuccessful on each occasion.
In a series of letters, between her and Newby, published in the periodical Athenaeum, Julia denied any such involvement and threatened legal action.
Eileen Fauset suggests that Julia may, in fact, have assisted Morgan with the novel at some point, but wanted nothing to do with the final version.
