I just went and checked Lily's page, and if it did ever say she had a daughter before, it does not now. The only entries under relatives that I saw was for Maleficent as her Mother (now confirmed), and her adoptive father (who has yet to be given a formal name that I am aware of).

While it would not be surprising that Lily had a daughter (seeing as she is the same age as Emma), I have not seen anything that officially makes that statement.
