Analysis

What the identification rests on, and the four offsets that hold it below certainty

Four threads tie John to Francis's household and none is a document naming him a son: a trade that ran father to son but through no surviving indenture; the East Anglia-to-London corridor that sent roughly three in five Massachusetts Bay emigrants of the 1630s and under one in ten from London proper; the 1634 liquidation that left an adult elder son nothing to inherit; and the Gurney and Rivett kin in the parish. Four offsets hold the case below certainty: the 1652/3 deposition age of "50 or thereabouts" reads five to eight years older than Entry E; John named no child Francis; no English marriage or child baptism of his own has been found; and both formal trade-admission registers return documented negatives. What removes the remaining doubt is negative — every other documented English John Gurney of the period has been traced to a life that rules him out, including thirteen Prerogative Court probate records fixing seven distinct John Gurneys in England after 1637 — while Anderson's Great Migration Directory still records the origin as "Unknown," which no surviving record contradicts.
