SIGNIFICANCE

I.83 catalogs the Wikipedia article on George Bryan Cooper (politician) = STRONG-consilience match for I.65 Biographical 1899's 'George son of John G. Cooper Esq Sr who went to Michigan, was state treasurer.' Per the v193.18 strategic pivot off the Mulford Jr / John G Jr branch (now COMPLETELY dead-end), George Bryan Cooper is Generation 4 Daniel-Sr-Y-line candidate on a parallel branch:

Inferred chain (consilience-based, not primary-source-locked at parent-son level): 1. Daniel Cooper Sr 1695-1795 (G.27) 2. George Cooper Sr 1745-1801 (G.108) 3. John G. Cooper Esq Sr 1780-1822 (m. Eleanor Perrine per I.65) 4. George Bryan Cooper 1808-1866 (Wikipedia I.83) 5. ??? — children unknown at I.83-level; Y-line continuation depends on follow-up

If George Bryan married + had Cooper-male sons, his Generation-5 descendants would be ~60 years older than Mulford Jr's Generation-6 cohort, putting current 2026 carriers (if any) at Generation 7-9 = potentially still alive.

Early life (verbatim)

Cooper was born in Long Hill Township, New Jersey, where he attended the public schools. He moved to Ann Arbor, Michigan in 1830, and later to Jackson in 1835. In Jackson he engaged in mercantile pursuits and became postmaster of Jackson from 1836 to 1846.

Political career (verbatim)

He was a member of the Michigan State Senate 4th District, 1837–1838. He established an iron foundry at Jackson in 1840 and served in the Michigan State House of Representatives in 1842. He served as State Treasurer of Michigan from March 17, 1846 to March 13, 1850. He engaged in banking at Jackson in 1851.

In 1858 he defeated incumbent Republican William Alanson Howard to be elected as a Democrat from Michigan's 1st congressional district to the Thirty-sixth Congress, serving from March 4, 1859, until May 15, 1860. Howard contested the results in the U.S. House, alleging voting irregularities in several wards. Following its investigation, the House Committee on Elections reported that the sitting member, Cooper, was not entitled to his seat and that the contestant Howard was. The House passed resolutions to that effect on May 15, 1860, at which time Howard took the oath of office.

After Cooper's removal from office, he resided at New Bedford in Wall Township, New Jersey until his death.

Catalog implications

1. Strong-consilience match for I.65 'George son of John G. Esq → Michigan State Treasurer'

I.65 (Biographical 1899 Morris Co. NJ p. 326+) states: "John G. Cooper, Esq. (fourth child of George Cooper [son of Daniel Sr]; lived in the valley where his father did; m. Eleanor Perrine; their son George went to Michigan, was treasurer of that state)."

I.83 Wikipedia data corroborates at multiple levels: - Name "George" — matches - Michigan State Treasurer — matches (Wikipedia confirms 17 Mar 1846 - 13 Mar 1850) - Long Hill Township NJ birthplace 1808 — consistent with John G. Esq Sr's documented Long Hill residence per Littell I.4 + I.65 - NJ → Michigan migration — Wikipedia confirms 1830 Ann Arbor + 1835 Jackson move

Caveat (per CLAUDE.md verbatim discipline): Wikipedia does NOT name his parents. Parentage match to John G. Esq Sr is consilience-based inference, not primary-source-locked at the parent-son link. The Long Hill 1808 birthplace + Michigan-Treasurer career align cleanly with I.65's claim, but a primary-source (e.g., birth record, Long Hill church baptism register, family Bible, NJ probate naming George Bryan as son of John G. Esq Sr) would be needed to lock the link.

Primary-source verification paths: - [ ] Long Hill Twp / Basking Ridge Presbyterian baptism register c. June 1808 for George Bryan Cooper s/o John G. Cooper Esq × Eleanor Perrine - [ ] John G. Cooper Esq Sr 1822 probate (Morris Co. NJ Surrogate) — would name children including George (then age 14) - [ ] Wall Twp Monmouth Co. NJ 1866 probate for George Bryan Cooper — heirs + spouse named - [ ] Find A Grave NJ Monmouth Co. (Wall Twp area) — family panel may attest parents

2. NEW catalog data on George Bryan Cooper

Beyond I.65's bare claim, Wikipedia provides: - Full name: George Bryan Cooper (middle name = Bryan, possibly maternal-family namesake) - Birth date exact: 6 June 1808 - Death date exact: 29 August 1866 age 58 - Death location: New Bedford, Wall Township, Monmouth Co. NJ (NOT Michigan; returned to NJ post-1860) - Career detail: Postmaster Jackson MI 1836-1846 + MI State Senate 1837-1838 + iron foundry founder 1840 + MI House 1842 + MI State Treasurer 1846-1850 + Jackson banking 1851 + U.S. House 1859-1860 (removed)

3. "Bryan" middle name = possible Daniel Sr family connection

George Bryan Cooper's middle name "Bryan" is notable. Per I.4 Littell p. 92 + I.65, John G. Cooper Esq Sr's siblings (children of George Cooper Sr 1745-1801) included "Bryan Lafferty Cooper" — = identifiable Bryan-family-name in the Daniel Sr line. Possible interpretations: - George Bryan Cooper b. 1808 named after his uncle Bryan Lafferty Cooper (= John G. Esq Sr's brother, his paternal uncle) - "Bryan" was a Daniel Sr family-name pattern (possibly from Bryan-surname connection somewhere — needs investigation) - Coincidental middle name

This is a corroborating data point for the I.65 parentage inference: George Bryan Cooper carrying the Daniel-Sr-family-name "Bryan" supports his being a member of the Daniel Sr lineage.

4. Y-line continuation status: UNKNOWN from I.83 alone

Wikipedia does NOT identify: - George Bryan Cooper's spouse(s) - Any children - Any descendants

Y-line carrier status depends on these facts which I.83 does not provide. Follow-ups (in order of leverage):

5. Election irregularity context (background, not Cooper-Y-relevant)

George Bryan's 1859-1860 U.S. House seat was contested by William Alanson Howard for "voting irregularities in several wards" → Cooper unseated 15 May 1860. This is a notable historical detail but not directly relevant to Y-line research. Worth a flag in case Michigan press coverage of the election dispute names family members.
