Origin — age and baptism
John Gurney was born about 1602–1610, most probably in the middle of that span, around 1604–1608. No record gives his birth date; his age has to be triangulated from four handles, and they do not all point at the same year. One record most frequently used by Gurney genealogists is where a 1652/3 deposition records him as “aged 50 … or thereabouts” in— suggesting a birth about 1602/3, but it is a rounded number not a birth record and is likely an estimate. The probable East Dereham baptism record reads several years younger, about 1609/10; his daughter’s 1647 marriage requires him to have been a grown man by the mid-1620s; and the September 1611 marriage of his likely parents sits in quiet tension with all of it. The four datapoints have different evidentiary value, and several of them are wide ranges. But taken together they bracket a probable window of roughly 1604–1608 inside a wider possible window of about 1602–1610.
The one age John gave for himself
In a life that is well documented from 1641 to 1663, John Gurney stated his own age exactly once. Deposing in the Suffolk County case of Wilson v. Faxon — Suffolk Court Files no. 188, dated “17-1-[16]52-3,” that is 17 March 1652/3 in old-style reckoning — he is recorded as “John Gurney of Brayntree aged 50 Yeares or therea-abouts.”[1] Taken at face value, an age of fifty in the spring of 1652/3 places his birth about 1602 or 1603. It is the strongest single anchor on his age, and the only one that indisputably belongs to the emigrant himself rather than to a record about his property or his household. Evidence
A rounded age, not a birth date
That fifty is not a measurement. It is a round number, offered “or thereabouts,” of exactly the kind early-modern deponents produced when asked their age — a formulaic self-report given to the nearest five or ten rather than the nearest year. The tendency of people in this period to round their stated ages to convenient figures is well documented: self-reported ages cluster heavily on multiples of ten and five, so a witness who says “about fifty” may in truth be anywhere from his middle forties to his middle fifties.[2] So the deposition does not narrow John’s birth to 1602/3 so much as it centres a band there: read strictly it gives 1602/3, but once the rounding is allowed for, its probable birth range is about 1603–1608 weighted by the other datapoints and its possible range widens to roughly 1598–1610. The age is real evidence that John was an older rather than a younger man, but it is a soft point, not a hard one. Evidence
The baptism reading and the parents’ 1611 marriage
A second, independent line reads John’s age from the English side and comes out younger. The identity research reads a degraded East Dereham baptism entry — indexed by Findmypast/FreeREG as “John the sonne of Nicholas Gorne,” and re-read on structured paleographic comparison as “John the sonne of ffrancis Gurnie,” about 1609/10 — as the probable baptism of John Gurney as the eldest child of Francis Gurney. That identification, its letterform tests, and the whole Candidate-B parentage argument are canonical in the identity work and the Francis Gurney (G14) companion, and are not re-argued here; what bears on age is only the date it implies, about six to eight years younger than the deposition’s 1602/3. The entry carries a ±2-year margin where the page year is not visible, so its early edge (about 1607) already closes much of that gap.[3]
The marriage of John’s likely parents adds a fourth handle — and a genuine friction. On 23 September 1611, “Franc Gurny & Margaret Rybett” were married at St Martin at Palace, Norwich.[4] If the East Dereham identification holds, a John baptised about 1609/10 as their child would have been born a year or two before his parents married — not impossible, but less common than a birth after the wedding, and enough to put the baptism reading under some strain. That strain cuts two ways: it can be eased by reading the baptism at the late edge of its margin (nearer 1611), or it can be set aside, because the marriage is the softest of the four handles. A child can be conceived and born independently of the date a couple formally married, and the parentage identification behind it is itself probable rather than proven. The marriage record is not in doubt; what it constrains is. So it is best read not as a fifth vote for a birth year but as a reminder that the whole East Dereham picture carries chronological tension the single-year readings gloss over. Evidence
A probable window and a possible one
A third handle constrains the birth from the far side and is independent of both the deposition and the baptism: John’s marriage by the later 1620s. His daughter Mary married Daniel Shed at Braintree in 1647, and Daniel was baptised at Finchingfield, Essex, in 1620 — bounding Mary’s own birth to by about 1628 and the couple’s English marriage to the mid-1620s, so that John was already an adult, plausibly in his early twenties, by about 1625. That bound sits comfortably with the earlier end of the range.[5]
Because each handle is uncertain in its own way, the honest picture is not a single year but two nested ranges, evaluated for each handle on its own terms:

The three birth-year estimators — the deposition age, the baptism reading, and the bound from Mary’s marriage — overlap around 1604–1608, and that overlap is the most probable window for John’s birth. Widen each to its possible range and the outer span is about 1602–1610, with the deposition alone — under the fullest allowance for rounding — reaching back toward 1598. The colonial chronology (the deposition and the marriage bound together) pulls toward the earlier half of that span; the identity-side baptism pulls toward the later half; the parents’ marriage, taken literally, would pull later still. None is decisive, and no colonial record states John’s birth or age beyond the single deposition, so his own baptism stays unproven on independent evidence. The best that the record supports is a birth about 1602–1610, most probably around 1604–1608. Evidence

The full Wilson v.

The ±one-decade band this rounding implies for a stated “about 50” is applied here only as an interpretive caveat on the deposition age. Source ID:
