Negative result

No early American arms witness found (open web search)

No early American physical or manuscript witness to the claimed Gurney arms use — bookplate, ex libris, Bible plate, seal, gravestone, or family paper — has been located for the Braintree/Weymouth line. A variant web sweep (Gurney/Gurnee/Gourney/Gurny, paired with those object terms) surfaced only the same 1926 American Biography derivative account. The absence does not settle the question: a genuine early object could sit in a private family collection, historical society, or local museum outside the reach of an open web search.

Confidence: Moderate-high

Search scope

  • Searched: Open web search (Google Books and general web) — Variant Gurney/Gurnee/Gourney/Gurny web search for an early American arms object or manuscript witness (bookplate, ex libris, Bible, seal, gravestone, plate)
  • Coverage window: 2026-06-01 to 2026-06-30
  • Search: Search for an early American physical or manuscript witness tying the Braintree/Weymouth Gurney line to the claimed inherited Gournay arms, beyond the 1926 American Biography derivative account.
  • Limitations: An open web search cannot access private family collections, unlisted historical-society holdings, or local museum objects that might carry an early physical witness.; The search was not run as a systematic pass over Google Books' full corpus, only via targeted variant queries.; No physical archive (NEHGS, Massachusetts Historical Society, or similar) was directly queried for a Gurney bookplate, seal, or arms-bearing object.
