John Field b. 1705 who married Mary Howard in 1726 at Bridgewater, Massachusetts Bay had a son John in 1727. Sources differ about the wife and children of this son: he is either

or

The evidence makes it pretty clear that the former profile is the correct John born 1727. I include the evidence and analysis below.
My question is about the second profile: at least two sources incorrectly attribute him as child of John and Mary (Howard) Field and thereby give him a birth year of 1727. So there are many family trees that include this information. If his marriage to Hannah Blackman in 1760 was his first marriage, then it is quite likely that he was born later than 1727. I could put down a date guess of, say 1735 or 1740, but I fear that people will try to create his profile and, by putting in 1727 as the birth year, not see the existing one and create a duplicate. So I am inclined to leave the birth year as 1727, although it is rather specific and probably wrong.
What is the best course of action? Right now I have set it as "after 1727", although I have no proof of that and that seems to make the status more certain than it really is. Is 1727 with uncertain better? Or some other approach?
Evidence that Field-4464 is the John b. 1727 to John and Mary (Howard) Field: John who married Mary Howard has a double gravestone with his father, on which they are named John 3rd and John 4th. There is a gravestone in Providence that says John Field son of John 4th, and lists birth year as 1727 and death year as 1794. So it's pretty clear this is the gravestone for the John son of John and Mary (Howard) Field.
That John left a will in 1794 in which he names his wife Lydia (living) and several children. The marriage to Lydia in 1748 occurs in the Rhode Island VR, as do the births of three of the children named in the will, so Lydia was alive and married to John at the time of the 1760 marriage of John Field and Hannah Blackman.
