Ancestry Family Tree — 'Theodosia Cooper' (b. 1775/1776 White House Hunterdon Co.

Searle candidate per I.85 = sister Catherine Elizabeth Wyckoff (b. 1799 d. 1884) m. Oct. 6, 1827 Zetus Searle (1799-1880) = ROOT of the existing catalog Wyckoff-Searle 4-generation chain ([F.5](../F-Church-Vital/F.5.yaml) + [D.7](../D-Federal-Census/D.7.yaml) + [D.15](../D-Federal-Census/D.15.yaml) + [D.21](../D-Federal-Census/D.21.yaml)).

Transcription and notes

SIGNIFICANCE — RESTORES THE CDV-LINE BENJAMIN → JOHN → JOHN D. CHAIN

L.72 captures the Ancestry Family Tree facts panel for Theodosia Cooper b. 1775/1776 White House Hunterdon Co. NJ — d. 29 Apr 1839 Williamsburg NY, identified as the 'Theodosia Wyckoff' of the H.2 CDV reverse caption per disambiguator-search v193.36-v193.37 2026-05-13.

3 major catalog impacts:

1. Theodosia identified — CDV-line disambiguator locked at tree-level

Per CDV: 'John D. Cooper, age 65 — son of Jno. Cooper who was brother of Theodosia Wyckoff — mother of E.C. Searle — who is Mother of H.E. Hussey'. L.72 identifies Theodosia as Cooper-born + Wyckoff-married 1794, matching the CDV caption's surname change.

2. Theodosia = Benjamin Cooper 1741-1794's daughter (per tree)

This is the catalog-changing finding. If primary-source-verified, the chain Benjamin → John Sr. → John D. Cooper (= CDV subject) is RESTORED.

Per project pr.12 Benjamin daughters per Littell.md Craddock framework, Benjamin's daughters per Craddock = Polly + Catharine + Charity. Theodosia NOT in Craddock list = Craddock incomplete (= now established via L.72).

3. NEW Benjamin-wife candidate: Catherine Haviland 1733-1803

Per tree, Catherine Haviland (= Theodosia's mother) was Benjamin's wife. She could be: - Benjamin's 2nd wife per Craddock framework (= the 'unknown 2nd wife' who had SON JOHN) → would mean Catherine + SON JOHN + Theodosia all same family branch - Different wife (= Craddock framework incomplete on wives too)

Catherine Haviland b. 1733 d. 4 Nov 1803 New Brunswick Middlesex NJ. NEW catalog person. Age 8 yrs older than Benjamin (b. 1741); older-wife pattern not uncommon. Haviland family-of-origin TBD.

This tree carries known errors: Benjamin's parents shown as "Unknown" (not linked to Daniel Sr) and a 31 Oct 1753 Monmouth marriage to Catherine Haviland = the C.1 Benjamin-Jr. conflation (our Benjamin was age 12 in 1753; see p.2). Useful for the Theodosia=Benjamin's-daughter link; unreliable on wife/parentage specifics. ~~Candidate contact re: Theodosia's brother John + his children (the p.671 CDV-subject lead).~~ 2026-06-18: owner-contact DEPRIORITIZED — maintainer confirmed the tree lists only Theodosia as Benjamin's child (no son John), so it carries no John-Sr/John-D. line and the owner (with the Haviland/1753 error in place) likely just copied Theodosia from a shared source. Does not advance the p.671 CDV-subject lead.

Catalog implications

1. CDV-line chain RESTORED (pending primary-source verification of Benjamin parentage)

Per L.72: Theodosia Cooper (b. 1775) = Benjamin Cooper's daughter. Theodosia's brother John Cooper Sr. = Benjamin's son = John D. Cooper (CDV subject)'s father. Chain restored.

Pre-L.72: chain was MEDIUM-HIGH consilience NOT primary-source-locked (per todo.md v193.34 pre-discovery).

Post-L.72 + corroborating sources: chain is multi-source consilience LIKELY accurate: - CDV inscription (secondary, family-memory) - Craddock framework (secondary, project pr.12 Benjamin daughters per Littell.md) - L.72 tree (Ancestry tree, low-tier) - L.73 tree (1855 Theodosia great-granddaughter, low-tier) - F.107 Blenheim Dutch Reformed Harriet 1804 birth (primary-source-grade independent corroboration of Theodosia's daughter Harriet) - F.108 Blenheim Dutch Reformed Jacob H[?] 1802 birth (2nd primary-source-grade independent corroboration of Theodosia's son Jacob Harvey)

The Theodosia-Cooper-Wyckoff identification is now corroborated at multiple-source level. Primary-source-locking the Benjamin-parentage requires: Theodosia's baptism record c. 1775 Hunterdon NJ + Benjamin's 1794 will (if extant) naming daughter Theodosia.

2. ~~E.C. Searle candidate-match = Elenor Conover Wyckoff~~ → v193.40 RE-IDENTIFIED = Catherine Elizabeth Wyckoff Searle (per I.85)

L.72 v193.36-v193.39 hypothesis: E.C. Searle = Elenor Conover Wyckoff (8th child of L.72) based on E.C. initials match. PRIOR READING: "If Elenor married a Searle, she became E.C. Searle."

v193.40 I.85 The Wyckoff Family in America 1950 published-source DISCONFIRMS the Elenor hypothesis: Wyckoff book entry #130 explicitly lists Elinor Conover Wyckoff (b. Mar. 18, 1813 — d. Apr. 1, 1908) as married to Mott S. Cannon then Dr. Stephen Childs — NO Searle marriage anywhere in entry #130. Elenor's Cannon-Childs children are Le Grand (d. infant) + Le Grand (m. Elizabeth De Pew with 4 grandchildren) + Newton (m. Louise Mellet) per I.85 — none Searle.

NEW E.C. Searle candidate per I.85 published-source = Catherine Elizabeth Wyckoff (b. Apr. 1, 1799 — d. June 27, 1884) m. Oct. 6, 1827 Zetus Searle (1799-1880) = sibling #2 of L.72's 11-children list (was 'no spouse listed' at L.72 v193.36 = unstated in L.72 source tree, now filled in via I.85 published-source). Initials reversed (C.E. ↔ E.C., common 19th-c. name-rendering pattern).

Catherine Elizabeth × Zetus Searle 1827 = ROOT of existing catalog Wyckoff-Searle 4-generation chain primary-source-attested at F.5 + D.7 + D.15 + D.21: - Generation A (NEW per I.85): Catherine Elizabeth Wyckoff × Zetus Searle Sr m. 1827 NJ - Generation B (D.15 1870 census): Zetus S. Searle Jr (b. ~1828 NJ) × Rebecca Bostwick Martin (b. NY); occupation 'Tea Aker'; Cortlandtown Westchester NY - Generation C (F.5 1888 marriage): Edward Searle (groom; parents = Zetus S. Searle + Rebecca Bostwick Martin per F.5) × Fanny Wyckoff (= L.73 Wyckoff cousin); m. 18 Sep 1888 Manhattan - Generation D (D.21 1910 census): Edward + Fanny W. Searles co-resident Manhattan Ward 16 W. 20th St.; no children listed in D.21

D.7 may be Zetus Searle Sr (1850 NYC Ward 18 head 'Zetus Searle' Clergyman age '34 [?]') OR Zetus Sr's son (= Zetus Jr); age '34' reading from D.7 conflicts with I.85 Zetus Sr b. 1799 (= 51 in 1850); needs re-read of D.7 image to disambiguate Sr vs Jr.

Verification path post-I.85 (replaces prior Elenor-Searle search): - NJ Marriage Records 1820-1830 for Catherine Elizabeth Wyckoff × Zetus Searle 1827 (= primary-source for the marriage I.85 names) - 1830/1840/1850/1860/1880 federal census for Catherine Elizabeth + Zetus Searle Sr household + children - Find A Grave memorials for Catherine Elizabeth Searle b. 1799 NJ + Zetus Searle Sr b. 1799 NJ - ** J.7 Geneanet 'SEARLE HUSSEY' 95-individual combined-surname listing** = stub [not yet uploaded]; high-priority pull = could directly identify H.E. Hussey via Catherine Elizabeth's daughter line per CDV H.2 caption

3. NEW Benjamin-wife: Catherine Haviland 1733-1803

Per L.72: Catherine Haviland = Theodosia's mother + Benjamin's wife. Death 4 Nov 1803 New Brunswick Middlesex NJ.

Per Craddock framework, Benjamin had 4 wives: Charity Hoff + Unknown 2nd + Mary + Anna Brown. Catherine Haviland could be the 'Unknown 2nd wife' who had SON JOHN per Craddock.

If verified, Catherine = mother of SON JOHN (= John D. Cooper Sr.) + daughter Theodosia + possibly others.

Catherine Haviland's family-of-origin: TBD. The Haviland family is well-attested in colonial NJ (Long Island origin + spread to NJ in 1700s).

4. NEW catalog persons surfaced via L.72

12 new catalog persons (Theodosia + her 11 children) + 2 more (Catherine Haviland + Jacob Wyckhoff). Plus the inferred-but-not-attested John Cooper Sr. (= Theodosia's brother, Benjamin's son).

5. Geographic migration trail of Theodosia + family

Theodosia's birth + marriage + children + death span: - White House, Hunterdon Co. NJ (b. 1775) - Monmouth, NJ (marriage 1794) - Blenheim, Schoharie Co. NY (several child births 1795-1820 = family lived in Schoharie NY part of the time) - Hunterdon, NJ (several child births = also lived in Hunterdon NJ) - Morristown, Middlesex Co. NJ (Elenor's birth 1813) - New Brunswick, Middlesex NJ (mother Catherine's death 1803) - Williamsburg, NY (Theodosia's death 1839)

Multi-state NJ/NY migration pattern. This affects where John Cooper Sr. (Theodosia's brother) might be found = same NJ/NY corridor.
