Found-in-Ancestry-trees panel [low certainty — tree-builder data]

Per memory feedback_ancestry_family_trees_low_certainty.md, this section is treated as a research lead, not as evidence.

• Highlighted tree: Cooper Family Tree (tree owner not visible in this view)
• Profile shown: Abraham Cooper
• Spouse: Nancy Anna Wills
• Father: Nathan I. COOPER
• Mother: Mehitabel (Hetty) SEWARD
• Children: Brig. General Nathan, Abraham
• Birth: 18 Feb 1762 Chester, Morris, New Jersey, USA
• Death: 18 Sep 1818 New Jersey, USA
• Residence: 1800 Roxbury, Morris, New Jersey, USA

Tree-builder family structure (low certainty, must be verified): - Nathan I. Cooper (father; presumed = Nathan Cooper Sr. of Roxbury, d. 1788, per J.35) married Mehitabel "Hetty" Seward. - Sons (per tree): Brigadier General Nathan Cooper + Abraham Cooper (b. 18 Feb 1762 Chester, d. 18 Sep 1818 NJ). - Per tree, Abraham married Nancy Anna Wills. - Note: the J.35 1788 will of Nathan Cooper Sr. names sons Henry, James, Nathan Jr., Davenpoort — not Abraham. Either (a) Abraham is from a different Nathan Cooper Sr. (the d. 1797 one in Roxbury per the Ancestry results below), (b) the tree mis-identifies Abraham's father, or (c) Abraham was disinherited / pre-deceased and not mentioned. Treat as [?] until reconciled with the will.

A long sequence of Chester Twp. ratepayer entries for Nathan Cooper, paired (likely Sr./Jr. or two tax-list events per year):

• 1802 Chester (×2)
• 1803 Chester (×2)
• 1805 Chester (×2)
• 1806 Chester (one entry, indexed as "Nathan Copper" — [indexing artifact] per the same Coopper-vs-Cooper noise documented in D.79-D.83 for Hanover)
• 1807 Chester (×2)
• 1808 Chester (×2)
• 1809 Chester (×2)
• 1810 Chester (×2)
• 1811 Chester (×2)
• 1812 Chester (×2)
• 1813 Chester (×2)
• 1814 Chester (×2)
• 1815 Chester (×2)
• 1817 Chester (×2)
• 1818 Chester (×2)
• 1860 Chester Township: Nathan A. Cooper + Nathan A. Jr. Cooper (third-generation Sr./Jr. pair).

Pattern observation: The same Sr./Jr. pairing structure documented for Hanover Twp. William Cooper (D.75-D.83) appears here for Chester Twp. Nathan Cooper, with the same 1800s-1810s tax-event pairing convention. Consistent — these are routine ratepayer lists. Two-entries-per-year may indicate June + August tax events for the same ratepayer (per D.79 finding) rather than two distinct Sr./Jr. ratepayers; the 1860 entry showing explicit "Nathan A." + "Nathan A. Jr." suggests by mid-19th-century the Cooper family did have an explicit father-son Sr./Jr. pair in Chester.

U.S. Family History Books

Multiple result rows for "Nathan Cooper": - Birth Chester, Morris County (multiple entries) - Birth Chester, Morris Co., N.J - Birth Roxbury US. Morris Co. N.J

Significance for the Benjamin-Cooper catalog

• Definitively retires the "J.33 Deed 4 witness Nathan Cooper Junr might be a Benjamin son" hypothesis. The Nathan Cooper figures surfaced by this search are all Roxbury / Chester, Morris Co. Coopers — a separate Cooper family from Daniel Cooper Sr.'s Long Hill / Passaic Twp. line.
• Together with J.35 (the 1788 Nathan Cooper will), the Roxbury Cooper family is now a coherent secondary cluster the catalog can recognize and set aside as out-of-scope per memory feedback_cdv_scope_benjamin_male_descendants.md.
• Triggers re-tag of all "Nathan Cooper" rows in J.31 / J.32 Morris Co. deed indexes as Roxbury-cluster (not Benjamin-line) entries. See J.31 / J.32 cross-references in J.35.
• Triggers re-tag of all "Abraham Cooper" Chester-Twp. ratepayer rows in D.78 as Roxbury-cluster (not Benjamin-line) entries. The Abraham Cooper of Chester (per D.78, ratepayer 1809-1818) is plausibly the same Abraham Cooper b. 1762 Chester per the Ancestry tree — a son of Nathan I. Cooper.

Status / follow-up

• Filed [verbatim] for what's in the search results PDF; tree-builder data section flagged [low certainty].
• The two "NOT YET PULLED" leads (Nathan Cooper Sr. d. 1797 Roxbury will; Nathan M Cooper d. 1811 Chester will) are deprioritized because the Roxbury Cooper family is out of scope for Benjamin-descendant research.
• Results 51-53 of 53 not visible in the captured 8-page PDF — would require a second screenshot if completeness is desired (low priority).
• No catalog action items follow from this search. The lead is closed.
