Price's Northampton data run to 1770, so a 1769 completion date is unsupported by his own text

Walford's 1885 essay dates "the accomplishment of this last result by Dr. Price" to 1769 (claim-walford-three-period-taxonomy-places-amicable-in-speculative-era). Price's first edition (claim-price-1771-first-edition-prints-northampton-table-as-appendix-table-iv) tabulates All Saints burials "from 1735 to 1770, or 36 years," and gives town-wide christenings and burials "for 28 years, from 1741 to 1770." A table built from deaths through 1770 cannot have been completed in 1769; the earliest plausible date is 1770–71. That is an inference from the data window, not a statement by Price about his working dates.

The only 1769 in the first edition's discussion belongs to the Norwich series: "I have been favoured with a copy of these bills for 30 years, from 1740 to 1769" (p. 257). Whether Walford's 1769 derives from this is speculation and is not asserted here.

Flag: [unverified-quote — Walford's passage was not re-read] in this pass. What Walford meant by "this last result" is unconfirmed, so the note stays a seedling. Walford's 1769 remains a secondary assertion and should not be promoted as the table's date of first publication.
