Negative result

No English John Gurney household outside the named candidates carries a Richard, John Jr., Peter, or Isaac

A search anchored on the colonial John's two rarest children's names -- Richard and Isaac -- across every English collection FamilySearch indexes returns exactly one Richard Gurney baptism with a father named John (Richard Gurnie, baptized 15 December 1626, St Peter, Hertfordshire -- Candidate C's own already-eliminated Richard) and zero Isaac Gurney baptisms with a father named John. No English John Gurney household anywhere, outside the candidates already named, carries a Richard, a John Jr., a Peter, or an Isaac in any combination. This is not treated as a definitive elimination on its own: it is equally consistent with the colonial John fathering his distinctive children entirely in Massachusetts after his June 1641 emigration, which is what the colonial record in fact shows.

Confidence: Moderate-high

Search scope

  • Searched: FamilySearch — Records (all collections)
  • Coverage window: 1620-01-01 to 1650-12-31
  • Search: Baptism of a child named Richard Gurney or Isaac Gurney (and spelling variants) with father John Gurney (and variants), England, filtered to results tagged 'Principal' for the baptized child
  • Results reviewed: 675
  • Limitations: FamilySearch's cross-collection index does not cover every English parish register or non-conformist record, so an unindexed Richard or Isaac baptism could exist outside this search.; The search filtered to entries tagged 'Principal' for the baptized child; a mis-tagged or mis-indexed entry naming father John could have been missed.
