The Wyckoff Family in America (1950, 2nd ed., Wyckoff Association in America, Summit NJ; ed. Streeter 1934; comp. William Forman Wyckoff) — printed pp. 287–288 entry #56 (=52.) JACOB6 WYCKOFF × THEODOSIA COOPER family = published-source-grade verbatim Wyckoff-genealogy entry naming all 11 children with marriages + dates. MULTI-CORRECTION of L.72/L.74 tree-tier readings: (a) child #6 1808 = Fanny Cooper Wyckoff (NOT James Cooper Wickoff per L.72; resolves the L.72/L.74 conflict in favor of L.74 Fanny reading); (b) Jacob's son (L.72 #3) = Jacob HARVEY Wyckoff at published-level (= primary-source-supersedes the F.108 high-res 'Henry' zoom reading); (c) child #5 = Simon I. (NOT Simon J. or Simon P.); (d) Gertrude's 2nd marriage (Cross) date = Dec. 9, 1814 (NOT 1817 per L.74 + NOT 1812 per F.109). MAJOR CDV-LINE FINDING — E.C. SEARLE RE-IDENTIFICATION: Wyckoff book identifies child #2 Catherine Elizabeth Wyckoff (b. Apr. 1, 1799 — d. June 27, 1884) m. Oct. 6, 1827, Zetus Searle (b. Mar. 13, 1799 — d. May 12, 1880) = Catherine Elizabeth Wyckoff Searle is the strongest E.C. Searle candidate per CDV [H.2](../H-Photograph-CDV/H.2.yaml) caption. DISCONFIRMS L.72's hypothesis that 'E.C. Searle' = Eleanor Conover Wyckoff: Wyckoff book entry 130 explicitly lists Eleanor C. Wyckoff (b. Mar. 18, 1813 — d. Apr. 1, 1908) as m. Mott S. Cannon, m. (2) Dr. Stephen Childs — NO Searle marriage. New datum: Jacob Wyckoff baptized Apr. 23, 1775 in Hunterdon Co. NJ (= same era + place as Theodosia b. 1775/76 White House Hunterdon = same baptismal church candidate). STILL NOT primary-source-locked: Theodosia Cooper's parents (Wyckoff book is silent on her parentage; doesn't confirm Benjamin Cooper 1741-1794 hypothesis from L.72)

Transcription and notes

SIGNIFICANCE — published-source-grade Jacob × Theodosia Wyckoff entry; multi-correction of L.72/L.74 tree-tier readings; E.C. Searle re-identification = Catherine Elizabeth (NOT Eleanor); SILENT on Theodosia's parents

I.85 = the verbatim entry for Jacob6 Wyckoff × Theodosia Cooper from "The Wyckoff Family in America" (1950 second edition, ed. Streeter 1934, compiled by William Forman Wyckoff). Printed pages 287-288 = entry #56 (= old-edition #52). Located 13 May 2026 v193.40 during Theodosia Cooper c. 1775 baptism research per todo.md priority queue.

Why this entry matters at catalog level (5 catalog impacts):

1. Published-source-grade verbatim list of all 11 Theodosia × Jacob Wyckoff children with dates + marriages + spouses = supersedes L.72 + L.74 Ancestry-tree-tier (per memory feedback_ancestry_family_trees_low_certainty.md).
2. Resolves L.72 vs L.74 conflict on the 1808 child = published-source unambiguously Fanny Cooper Wyckoff (NOT James Cooper Wickoff) = L.74 reading correct, L.72 reading wrong.
3. Resolves F.108 Jacob H[?] middle-name uncertainty = published-source = Jacob HARVEY Wyckoff (= supersedes maintainer 2026-05-13 high-res zoom reading 'Henry' per memory feedback_secondary_source_middle_initial_caution.md).
4. ** MAJOR CDV-LINE RE-IDENTIFICATION OF E.C. SEARLE: - L.72 hypothesized E.C. Searle = Eleanor Conover Wyckoff based on initials match. - I.85 published-source = Eleanor m. Cannon + Childs, NEVER Searle. - I.85 published-source = sister Catherine Elizabeth Wyckoff m. Zetus Searle Oct. 6, 1827** = strongest E.C. Searle candidate (initials reversed, common in 19th c). - = significantly changes the H.2 CDV-caption disambiguation chain identity.
5. Theodosia's parents NOT stated in book = published-source SILENT on Benjamin Cooper 1741-1794 parentage hypothesis from L.72. Does NOT primary-source-lock the Benjamin → Theodosia parent-child link. Locking still requires (a) Theodosia's c. 1775 Hunterdon Co. NJ baptism record naming father Benjamin OR (b) Benjamin's 1794 will/probate naming daughter Theodosia OR (c) Cooper-side genealogy (e.g., Littell I.4 Craddock framework or further Cooper-family records) explicitly listing Theodosia as Benjamin's daughter.

#133 MALVINA THEODOSIA

133. MALVINA THEODOSIA7 WYCKOFF (Jacob6, John5, John4, Simon3, Cornelius Pieterse2, Peter Claesen1), born Sept. 8, 1820, at Basking Ridge, N.J.; died May 29, 1892, at Sterling, Ill.; married Dec. 15, 1839, Edward Thomas, born 1818, died 1900.

    Children (Thomas):

        FRANCES MALVINA, born Dec. 21, 1840; died May 22, 1923; married Mar. 9, 1866, Flavel Simonson. No issue.

        EDWARD WYCKOFF, born Dec. 1, 1842; died Dec. 2, 1898; unmarried.

Searle as middle name for Malvina Theodosia × Edward Thomas's daughter = corroborates strong Wyckoff-Searle family connection across multiple cousins. Catherine Elizabeth Wyckoff × Zetus Searle 1827 (the family-prominent Searle marriage) was apparently family-prominent enough that 23 years later her sister Malvina Theodosia named a daughter "Etheta SEARLE" as middle-name namesake (= a cousin of Catherine Elizabeth's children).

Catalog implications (5 catalog impacts post-I.85)

1. Multi-correction of L.72/L.74 tree-tier readings at published-source level

2. MAJOR CDV-line E.C. Searle re-identification

L.72 hypothesized: E.C. Searle = Eleanor Conover Wyckoff (b. 1813), based on initials match.

I.85 published-source DISCONFIRMS L.72 hypothesis at #130 entry: Eleanor Conover Wyckoff m. Mott S. Cannon, then Dr. Stephen Childs, NOT Searle.

I.85 NEW E.C. Searle candidate: Catherine Elizabeth Wyckoff (b. Apr. 1, 1799 — d. June 27, 1884) m. Oct. 6, 1827, Zetus Searle (1799-1880). Initials reversed (C.E. ↔ E.C., common in 19th-c. records).

Catalog implication for H.2 CDV caption chain: The chain becomes Theodosia Wyckoff → daughter Catherine Elizabeth Wyckoff Searle → daughter (TBD) named with H.E. initials → m. Hussey. Wyckoff book is silent on Catherine Elizabeth's children = need separate Searle/Hussey-family source.

3. Theodosia's parents — NOT primary-source-locked at I.85 level

I.85 SILENT on Theodosia's parents. Wyckoff book gives Jacob's full Wyckoff lineage but does NOT name Theodosia's father. L.72 tree-tier hypothesis Benjamin Cooper 1741-1794 = remains unverified at published-genealogy level. Locking still requires Cooper-side source (baptism record, will, or Cooper-genealogy work like Littell/Craddock framework).

Implication for v193.39 todo.md priority: the 'Theodosia Cooper baptism c. 1775 Hunterdon Co. NJ' follow-up is STILL TOP-PRIORITY post-I.85. I.85 narrowed where she'd likely be baptized (= same Hunterdon-Co. region as Jacob's Apr. 23, 1775 baptism, possibly same church) but did NOT itself confirm her parentage.

4. NEW data points surfaced via I.85

• Jacob Wyckoff baptized Apr. 23, 1775 in Hunterdon Co. NJ = NEW data point; suggests White House Hunterdon Co. NJ Reformed Dutch Church (= Readington DRC) or similar 1775 Hunterdon DRC was likely candidate baptism location. Same church likely baptized Theodosia c. 1775.
• Jacob × Theodosia removed from NJ to NY (per book): Schoharie NY (per L.72/F.107/F.108 children's birth records 1795+) → eventually NYC area where Jacob is buried.
• Jacob died Sept. 10, 1849 = confirms L.72 1849 death year at published level; new exact date.
• Theodosia died Apr. 29, 1839 = confirms L.72 death date at published level.
• Malvina Theodosia b. at Basking Ridge NJ Sept. 8, 1820 = Basking Ridge NJ as Wyckoff family residence in 1820 (= same town as Daniel Sr's burial per project pr.4 Daniel Sr buried Basking Ridge (RESOLVED).md; potential research lead for Cooper-family proximity).
• Multi-Searle marriage pattern: Catherine Elizabeth × Zetus Searle 1827 (sister) + Theodosia Cooper × Edward Searle 1881 (great-niece) + Fanny × Edward Searle 1888 (great-niece, after Theodosia's death) + Harriet Etheta Searle Thomas (cousin's middle name 1850) = strong Wyckoff-Searle family intermarriage cluster suggesting Catherine Elizabeth × Zetus Searle 1827 marriage created family connection that perpetuated.
• Fanny Cooper Wyckoff Daniel children born at Gilboa NY (entry #128 — 1834 + 1836 children) = Schoharie Co. NY area Wyckoff residence into 1830s+ (= same area as F.109 Conesville/Gilboa Dutch Reformed marriage of Gertrude × Stephenson 1812).

5. Strategic Y-DNA / outreach implication

Post-I.85, the Wyckoff line is autosomal (= Theodosia × Jacob children's Y-DNA = Wyckoff Y, NOT Cooper Y), so direct Y-DNA outreach to Wyckoff descendants ≠ relevant for Cooper Y. The catalog impact is on identification: confirms the L.72 family chain at published level + locks E.C. Searle as Catherine Elizabeth (NOT Eleanor) = changes which CDV-line forward-trace path is correct.

Per project pr.14 Two paths to Benjamin male descendants.md: Y-DNA path is unaffected; paperwork path = strengthened by confirmation that L.72 family is real (= corroborates Theodosia as a Cooper-line person, just not yet at primary-source-Benjamin-parent level).

Cross-references

• L.72 Ancestry tree Theodosia Cooper b. 1775 = primary catalog entry on Theodosia × Jacob Wyckoff family; tree-tier; I.85 published-source supersedes on multiple specific data points (see table above)
• L.73 Ancestry tree Theodosia Cooper Wyckoff b. 1855 great-granddaughter = primary-source-locked at I.85 published-Wyckoff-genealogy level (Theodosia × Edward Searle 1881 m. recorded in entry #127)
• L.74 Ancestry tree expanded biographical data for Gertrude Wyckoff Stevenson Cross = corroborated at I.85 published level on Gertrude's existence + dates; L.74's 1817 Cross-marriage date superseded by I.85's 1814

• F.109 Conesville/Gilboa Dutch Reformed Stephenson × Wyckoff marriage Jun 1812 = Gertrude's 1st marriage; I.85 confirms + adds 2nd marriage Dec. 9, 1814 to James Cross
• G.126 Find A Grave Gertrude Wyckoff Stevenson Cross Basking Ridge plot 500.1 = corroborated at I.85 published level on dates
• H.2 CDV reverse caption — E.C. Searle disambiguation chain; I.85 forces re-identification of E.C. Searle from Eleanor Conover (per L.72) to Catherine Elizabeth (per published-Wyckoff genealogy)
• G.28 Capt. Benjamin Cooper 1741-1794 = Theodosia's hypothesized father per L.72; I.85 SILENT on this parentage = does NOT primary-source-lock
• Project pr.12 Benjamin daughters per Littell.md Craddock framework — Theodosia's parentage hypothesis; I.85 does NOT corroborate at published level

Open questions / follow-ups post-I.85

HIGHEST priority

• [ ] ** Catherine Elizabeth Wyckoff Searle (1799-1884) × Zetus Searle (1799-1880) descendants** — = NEW E.C. Searle candidate per I.85; need separate Searle-family genealogy source naming her children + identify whether one daughter = H.E. Hussey per CDV H.2 caption. Search: NJ Marriage Records 1820-1830 Catherine Elizabeth Wyckoff × Zetus Searle; 1830-1880 federal census for Catherine + Zetus Searle household + children; Find A Grave memorials for Zetus + Catherine.
• [ ] ** Theodosia Cooper baptism c. 1775 Hunterdon Co. NJ — = STILL TOP-PRIORITY (I.85 didn't lock parentage). Specifically: Reformed Dutch Church of Readington (= White House area) baptism register 1775; Lebanon DRC; Three Mile Run; Bedminster DRC; Whitehouse Reformed Church; NJ Births and Christenings Index 1660-1931 search Theodosia Cooper b. 1775-76 Hunterdon. NEW LEAD per I.85**: Jacob Wyckoff baptized Apr. 23, 1775 in Hunterdon = same Hunterdon DRC may have Theodosia c. 1775 baptism record nearby = same-church search.
• [ ] ** Cooper-side genealogy source naming Theodosia as Benjamin's daughter** — Littell I.4 Craddock framework + further Cooper-genealogy works; may name Theodosia. Per project pr.12 Benjamin daughters per Littell.md: Craddock framework names Polly + Catharine + Charity = NO Theodosia. So either Craddock incomplete, OR Theodosia not Benjamin's daughter (= would falsify L.72 hypothesis at published level).
• [ ] ** Jacob Wyckoff (1775-1849) parents = John5 Wyckoff family** — book gives lineage but L.72/L.74 didn't capture Jacob's father John5; need to identify John5 Wyckoff (= Jacob's father) and his residence to triangulate Theodosia × Jacob marriage location.

Medium priority

• [ ] ** Re-verify L.72 conflict on Catherine Elizabeth's apparent absence of children** — Wyckoff book lists no numbered sub-entry for Catherine Elizabeth × Zetus Searle, but doesn't say "no issue"; she may have had children that book treats as outside scope. Search NJ vital records + census for Catherine Searle b. 1799 NJ children.
• [ ] ** Edward Searle (m. Theodosia Cooper Wyckoff 1881 + Fanny 1888) family-of-origin** — likely descendant of Zetus Searle 1799-1880 (= grandson or grandnephew); same Searle family. Verifies cluster.
• [ ] ** Update L.72 Catherine Elizabeth child #2 entry** to flag Zetus Searle 1827 marriage = E.C. Searle re-identification candidate (replacing Eleanor Conover)
• [ ] ** Update L.72 Eleanor child #8 entry** to NOTE Wyckoff-book disconfirmation of Searle-marriage hypothesis
• [ ] ** Update F.107/F.108 entries** with Wyckoff-book corrections (Harriet's spouse Abraham Van Horn 1825; Jacob HARVEY confirmed at published level)
• [ ] ** Update F.109 entry** to flag Gertrude's 2nd marriage = Dec. 9, 1814 Cross (NOT 1817 per L.74)
• [ ] ** Re-search Blenheim Dutch Reformed register for Fanny Cooper Wyckoff b. Dec. 11, 1808 baptism** (NOT James Cooper Wickoff per prior L.72 reading)

Lower priority

• [ ] ** Gilboa NY Wyckoff residence c. 1834-1838** — Fanny × Charles Daniel had children at Gilboa NY 1834 + 1836 = Wyckoff family Schoharie Co. NY residence into late 1830s. May be near Gertrude's Conesville/Gilboa marriage 1812.
• [x] ~~ Wyckoff Family in America 2nd-edition book — index pages 518-521 + 523 'COOPER' index entries sweep; verify no other Theodosia/Cooper-related entries elsewhere in book missed by initial grep.~~ DONE 2026-05-18 via pdftotext full-book sweep → I.92. Major find: entry #97 = John6 Wyckoff (Nicholas2 Pieterse branch) × Elizabeth Cooper born 26 Jan 1776 died 2 Nov 1860, lived near Mendham N.J. = candidate sister of Theodosia 1775. Plus 6 minor post-1830 Cooper-name finds (Amy / Franklin E. / Hattie 1873 Lyons NY / Harriette N. 1830 / Edward Whitehall 1918 / Gladys). NEW stub p.71 Elizabeth (Cooper) Wyckoff of Mendham.
• [ ] ** Wyckoff book 1934 1st-edition** — predecessor edition by Streeter; may have different content if found at archive.org or similar.
• [ ] ** H.E. Hussey identification** — was Harriet Etheta Searle Thomas (entry #133 sub-entry) ever known as H.E. Hussey? She m. Leffingwell + Dyer + Hanna per Wyckoff book = NOT Hussey. Looks like H.E. Hussey ≠ Harriet Etheta Searle Thomas. Need separate source.

Status notes

• Status [verbatim] — entry quotes Wyckoff book entry #56 + sub-entries #127-#133 directly; minimal interpretive content
• Certainty [high published-source certainty for Wyckoff descendants — covers 11 children + grandchildren + great-grandchildren; medium-high for cross-source corroboration of L.72/L.74 tree-tier; SILENT on Theodosia's Cooper parents = does NOT primary-source-lock the Benjamin Cooper 1741-1794 hypothesis from L.72]
• Per memory feedback_full_transcription_policy.md: I.85 captures full entry #56 + all relevant sub-entries (not just Theodosia-focused subset) since context relevant to multiple catalog cross-references
• Per memory feedback_secondary_source_middle_initial_caution.md: I.85 published-source corrects F.108 Henry/Harvey middle-name reading + L.72 child #6 James/Fanny gender reading at published level; these were tree-tier vs zoom-tier vs indexer-tier disagreements that the published genealogy resolves
• Located 13 May 2026 v193.40 during todo.md priority follow-up: 'Theodosia Cooper baptism c. 1775 Hunterdon Co. NJ — naming father Benjamin Cooper'. The original task remains unresolved — Theodosia's Cooper parentage NOT primary-source-locked at I.85 level. I.85 is a major collateral finding (= multi-correction of L.72/L.74 tree readings + E.C. Searle re-identification) but does NOT close the original baptism-record / parentage-lock task.
