Kelly, I don't see that the sources on this profile document Sarah (Morton) Currie as the daughter of John Morton.
Colonial Families of Philadelphia does not identify the daughter of John Morton. The Find-a-Grave memorial gives an inscription giving a relationship but there is no image to document the inscription or source of a transcription. And, the profile of John Morton is lacking any reference or documentation of his offspring.
It may be that the relationship you propose is correct but it should be properly documented to make the attachment to an historical figure.
May I suggest you add the tag 1776 to your question so that the project management team for that project sees your question. You can also directly contact SJ Baty.
