KEY DISCOVERY — COOPERS PLAINS, STEUBEN, NEW YORK

Dr. John Lewis Cooper Sr's eldest son Dr. John Lewis Cooper Jr was: - Born 26 May 1799 COOPERS PLAINS, STEUBEN, NY - Died 23 Oct 1863 COOPERS PLAINS, STEUBEN, NY

** Per CLAUDE.md preamble (master catalog directive):**

"The three Cooper family Bibles in Bible/ (Cooper Bible at NJHS, F S Cooper, John Cooper Bible) document the Cooper Plains, Steuben Co., NY → Ohio → Kansas → Colorado line (John Cooper + Elizabeth b. 1830s+ NY; Frederic Stephen Cooper 1846; Fred Merrell Cooper 1873; Edward Merrell Cooper 1881; Peggy Cooper 1915 Aspen; etc.) — this is Chris Cooper's own documented ancestry, and it is a separate Cooper line from Benjamin Cooper of Morris Co. NJ."

** CATALOG-DEFINING IMPLICATION: If Dr. John Lewis Cooper Jr (b. 1799 Coopers Plains) had a son John Cooper b. 1830s+ NY who married Elizabeth = this matches the Cooper Bibles' "John Cooper + Elizabeth" couple at Coopers Plains. Then Chris Cooper's documented family Bible line = Daniel Cooper Sr's descendant via Daniel Cooper Jr (= Benjamin's brother) → Dr. John Lewis Cooper Sr → Dr. John Lewis Cooper Jr → John Cooper b. 1830s → ... → Chris Cooper.**

This would mean Chris Cooper IS a descendant of Daniel Cooper Sr. (1695-1795 Long Hill NJ), just NOT via Benjamin (1741-1794) but via Daniel Cooper Jr (1729-1787). Chris's Y-DNA = Daniel Sr's Y-DNA in this scenario.

** BUT subject to Cooper-Coriell Y-DNA constraint per project pr.16 Cooper-Coriell Y-DNA mystery.md: Chris's Y-DNA matches Coriell (not Cooper). Possibilities: - (a) Chris IS descended from Daniel Sr but Daniel Sr was Coriell-haplotype = Daniel Sr's line was Coriell-named at some earlier generation, name-changed to Cooper before 1700 (= NPE / surname adoption / Sephardic-name-change theory per memory) - (b) Chris is NOT descended from Daniel Sr = the Coopers Plains NY connection is coincidence, multiple Cooper families in early NY frontier - (c) NPE somewhere in Chris's chain** = mid-line break in Cooper-Cooper inheritance

This is a CATALOG-DEFINING question requiring further investigation. The hypothesis-test path: 1. Identify John Cooper b. 1830s NY of Cooper Bibles — his parents named? 2. If parents = Dr. John Lewis Cooper Jr × spouse, the Daniel-Sr-to-Chris hypothesis confirms 3. Y-DNA reconciliation = whether Daniel Sr.'s Y-DNA is Cooper or Coriell-haplotype

Top hit = the Robert Wayne Setty tree (= L.30 tree). Other hits: - "John Cooper Fitz Randolph" name variant in Private + Public Photos (with NJ state seal image) - BGMI entries 2× under "John Cooper Fitz Randolph" 1846-1911 - Find A Grave Index: "John C.F. Randolph" 1846-1911 = our person - Newspapers.com Obit Index: "John R. Randolph" abt 1846 d. 1911 Newark Essex NJ — likely our person, indexed-name variation - Other John Randolphs (1844, 1847 b.) — different people, ruled out

No spouse + no children for our John Cooper Randolph confirmed across multiple sources. Y-line dead-end through this Randolph line (which was already not a Cooper Y-line anyway).

KEY FINDINGS

1. ** COOPERS PLAINS NY CONNECTION = potential Chris Cooper family lineage to Daniel Sr. Dr. John Lewis Cooper Jr (b. 1799 Coopers Plains NY) is the link point. Investigation REQUIRED**: identify John Cooper b. 1830s NY of Chris Cooper's family Bibles + test whether his parents = Dr. John Lewis Cooper Jr × spouse.

2. ** 11+ documented children of Daniel Cooper Jr (= Benjamin's brother) × Nancy Anna Cross + half-sister Catherine 1754-1783 by Daniel Jr's 1st wife. Massive expansion of Daniel Cooper Jr's family — previously catalog had Daniel Jr only as F.33/F.34 pew-holder + memory "d. 1787 suicide". L.30 documents 11+ children: - Lydia (1758-1795) - Mary Polly (1759-1831 — DIFFERENT from Benjamin's daughter Polly) - Peter (1761-1847 d. Basking Ridge — matches F.32 Peter Cooper × Susan Boyle 1808!) - William M (1763-1836 d. Fayette KY) - Dr. John Lewis Sr (1765-1851) - Stephen** (1767-1844 d. Long Hill — matches F.32 Stephen Cooper × Mehetable!) - Anna (1770-1847 d. Rahway) - Elizabeth Betsy (1773-1835 d. Union Co NJ) - Sarah Sally (1776-1852) - Daniel (1779-1850 d. Fayette KY) - Joseph (1782-1816 d. Fayette KY) - + half-sister Catherine (1754-1783)

3. ** F.32 baptismal register's "Peter Cooper" = Daniel Jr's son Peter (b. 1761 d. 1847)** — matches per geographic + age + Basking Ridge presence. F.32's Peter Cooper × Susan Boyle 1808 likely = this Daniel Jr's son Peter.

4. ** F.32 baptismal register's "Stephen Cooper" = Daniel Jr's son Stephen (b. 1767 d. 1844 Long Hill)** — matches. F.32's "Cooper, Robert, son of Stephen 5 July 1816" baptism + G.51's "Mehetable wife of Stephen" = this Daniel Jr's son Stephen.

5. ** Three Cooper brothers migrated to FAYETTE KY: William M (d. 1836) + Daniel (d. 1850) + Joseph (d. 1816) — major Cooper family Kentucky migration documented. NEW research direction:** Cooper family in Fayette Co. KY 1810-1850 = Daniel Jr's 3 sons + their descendants.

6. ** Daniel Cooper Jr birth year 1729 + half-sister Catherine 1754** = Daniel Jr was 25 when 1st daughter born; per project pr.4 Daniel Sr buried Basking Ridge (RESOLVED).md Daniel Jr d. 1787 by suicide age 58. Daniel Jr's 1st wife (Catherine's mother) deceased pre-1758; Daniel Jr m. Nancy Anna Cross c. 1758 (b. of Lydia 1758).

7. ** Mary Ellen Erwin (Dr. John Lewis Sr's wife) = "Erwin Family" book reference** per I.25. The book "The Erwin Family" likely traces Erwin family genealogy through this Cooper-Erwin marriage 1798. Mary Ellen Erwin's family of origin = Easton PA Erwin family.

8. ** Sarah Ann Cooper born EASTON PA (not NJ) on 18 June 1815** — christened back in NJ (= Basking Ridge Presbyterian) at her father's family church. Resolves F.35 location: birth PA, baptism NJ.

9. ** Sarah Ann Cooper buried EASTON PA** — went home to family burial place despite dying at Morristown NJ. Reflects strong Cooper-Easton-PA family ties across 3 generations (Dr. John Lewis Sr 1794+, his children Easton PA 1801-1854, Sarah Ann burial Easton 1904).

10. ** Sarah Ann Cooper marriage-date discrepancy 25 Sep 1840 (L.30 tree) vs 8 Sep 1840 (I.24 Christian + Fitz Randolph book).** L.30 tree cited 2 sources for date. Need primary-source resolution — possibly NJ or PA Marriage Records 1840.

11. ** Nancy Anna Cross (Daniel Jr's wife)** full name + birth/death dates 1737-1805 = expanded biographical data vs I.25's "Ann Cross" alone.

12. ** Sarah Ann Cooper's daughter Charlotte V Randolph (1842-1870 d. 27 DEC 1870 Jersey City NJ aged 28)** = died young; NEW death date primary-source-derivable from L.30 tree.

13. ** John Cooper Randolph (1846-1911) lifelong bachelor — confirms across L.30 tree + BGMI + multiple search results. Y-line carrier of Sarah Ann's autosomal-Cooper-DNA terminates with his death (no descendants).**

14. ** Joseph Randolph Jr Esq. (1843-1932) had no children per I.24. Sarah Ann's potential Cooper-autosomal-DNA forward-trace = ONLY through Charlotte V Randolph Vanderveer (1842-1870) + Mary E Randolph (1849-1927 unmarried)** — both daughters; the latter unmarried = no descendants; Charlotte V = married Vanderveer + had children, but died age 28 = limited descendants.

Catalog impact

• ** CHRIS COOPER PERSONAL-LINEAGE CATALOG-DEFINING DISCOVERY: Coopers Plains NY connection to Daniel Cooper Jr's son Dr. John Lewis Cooper Jr (b. 1799). Subject to primary-source verification of Chris's family Bible "John Cooper b. 1830s NY" parentage.**

Open questions / follow-up

• PRIORITY 1: Pull Chris Cooper's family Bible 'John Cooper + Elizabeth b. 1830s+ NY' parentage — does John Cooper's father = Dr. John Lewis Cooper Jr (b. 1799 Coopers Plains)? CATALOG-DEFINING question for Chris's personal lineage to Daniel Sr.
• PRIORITY 2: Pull Dr. John Lewis Cooper Jr (1799-1863) Ancestry tree page — would identify his children including possible "John Cooper b. 1830s NY" father of Chris Cooper's line.
• PRIORITY 3: Investigate Coopers Plains, Steuben Co. NY history — NY frontier town named for Coopers; Dr. John Lewis Cooper Jr born there 1799 = town pre-existed his birth. Identify town founding + Cooper-family role in establishment.
• PRIORITY 4: Identify Daniel Cooper Jr's 1st wife (mother of Catherine 1754-1783) — NJ marriage records 1750-1758.
• PRIORITY 5: Investigate Mary Ellen Erwin's family of origin Easton PA — pull "The Erwin Family" book per I.25.
• PRIORITY 6: Pull Fayette Co. KY records 1810-1850 for William M Cooper (1763-1836) + Daniel Cooper (1779-1850) + Joseph Cooper (1782-1816) — 3 Cooper-Kentucky brothers.
• PRIORITY 7: Resolve Sarah Ann Cooper marriage date discrepancy 25 Sep 1840 vs 8 Sep 1840 — pull primary-source NJ or PA Marriage Records 1840 + Easton PA marriage records 1840.
• PRIORITY 8: Update F.32 to identify Peter + Stephen Cooper as Daniel Jr's sons (not Benjamin's son's children). And re-evaluate which F.32 "John"-paternity entries belong to which John (Dr. John Lewis Sr vs Benjamin's son John).
