Reviewing the scant available information on John Farlow (Farlow-14), I would suggest that USSC leaders go ahead with the suggested disconnection and leave in its place a note with link that it has been made. A summary of notes and links is on his profile under Research Notes.
The only primary evidence of Farlow-14 possibly in Carolina comes from records used by Jackson for his substitute census index. That Farlow-14 was Quaker is perhaps questionable. He does not appear in extant Quaker records (Pennsylvania, Virginia or North Carolina) nor in the official extant colonial records of North Carolina. It is known that all of the mentioned records are incomplete. Hinshaw's surname index shows no known records of a Quaker Farlow or Farlo in Virginia but does show them in Goshen, Kennet and New Garden of Pennsylvania. However, specific records are not found in the Pennsylvania volume of Hinshaw's transcription of meeting minutes leading me to think the records are not transcribed or digitized (many are not in this period in this geographic area, see TriCollege Library research division which untranscribed index I have not yet searched).
The connection of Farlow-14 to Farley-754 appears to stem from someone's interpretation of a published family history where the earliest generations are unsourced and it clearly states multiple interpretations of what is listed. Farley-754 profile states that SAR "establishes" a connection when it clearly does not, appearing to rely upon a 1655 (headright?) record where the connection appears to rely upon similarity of surname and nothing more. The date of execution of Farley-754 is established as 1676. The record of an immigrant John Farley (with no documented relationship to to Farley-754) is dated 1655 indicating a birth some time prior to this. There is nothing to suggest a John Farlow is that person or that he was even alive in 1655 (or 1676). From what little information there is about John Farlow, a birth by 1676 or earlier is very dubious. The conclusion I draw from a review of what is known indicates that the detachment should be made.
