Henry Portal, the Bank of England's earliest confirmed paper supplier, was a Huguenot papermaker from Poitiers with no documented connection to Fabriano or Italian papermaking
Henry Portal (Henri de Portal, 1690–1747), whose firm won the Bank of England's earliest Tier-1-confirmed paper-supply contract in 1724, was French rather than Italian in origin. Per The Huguenots of Spitalfields, a specialist Huguenot-history organization: "Henri de Portal (1690–1747) was a papermaker who made the first watermarked paper for the Bank of England notes. The Portal family came from Poitiers and took refuge in Southampton." Portal was a Huguenot refugee, trained through Huguenot-run paper mills in Hampshire, not a documented heir to Fabriano's watermarking tradition or to Italian papermaking practice generally.
No source located in this vault — this capture's own search or any prior session's — documents a supply chain, apprenticeship, or technology transfer between Fabriano and English watermarking practice. This bounds how Fabriano's 13th-century watermark and the Bank of England's watermarked banknote paper genuinely relate: both are corrected by the same research method (checking the earliest surviving artifact rather than the popularized round date), but nothing found so far links them historically. The resemblance between the two vault threads is methodological, not genealogical.
