Analysis
The unknown-corridor residual: eliminating named households does not clear the record's gaps
Eliminating named households is not the same as clearing the record. The same-name sweeps found more than forty distinct John Gurney heads of household in England between 1600 and 1670, and English parish-register coverage for the period is patchy enough that others existed unrecorded. The 1662-1666 London hearth-tax cluster makes the point concrete: eleven Gurney households in London alone, none of them surfaced by any candidate search, because a search built around a name, a wife, and a child set cannot see a household the registers never entered. The identity case file expresses this same residual as its two unknown-corridor scenarios, and it is the principal reason the estimate for Candidate B sits in the sixties rather than the nineties.
Why this conclusion
- Depends on Evidence English parish, probate, and muster comparators clearing the remaining same-name fieldThe forty-plus same-name heads of household come from the English parish, probate, and muster clearance sweep.
- Supported by Evidence Eleven Gurney households in the London hearth-tax returns, 1662-1666Eleven London Gurney households none of the candidate searches surfaced are the density evidence for the unknown-corridor residual.
- Synthesized by Analysis Two realistic end-states for the estimate and three levers that would move itThe residual space is what a Norfolk marriage record or kin-mention would have to shrink.
Qualifications and conflicts
- Qualifies Identity hypothesis Candidate B: John was probably the son of Francis Gurney and Margaret RybettThe residual candidate space is the standing limit on the parentage hypothesis's probability.
Related context
- Provides context for Finding Candidate landscape: 45 eliminated, 5 unlikely, Candidate B the sole survivor; probability model external-canonicalThe candidate-landscape finding clears named households; this analysis states what that leaves uncleared.
