Searched for: HIS MARRIAGE - the gap the descendant sweep's worklist carried against him as "marriage record (to p.2132) - no date; no search recorded for this gap". Not a name search: the record id was already written in Ella (Sargent) Cooper's own body on 2026-10-24, harvested by fetch_findagrave.ps1 from memorial 14798762 and listed there under "Three Ancestry links, none opened". Opened: collection 61376 record 900415235, "New Jersey, U.S., Marriage Records, 1670-1965" - the New Jersey State Archives county marriage series, the same series as [C.115] and [C.117].
Result: DATED: 15 November 1898, Andover, Sussex County - Luella Sergeant, Female, Marriage Age 17, Birth Date abt 1881, Spouse Alfred A. Cooper, Film Number 004211081. IT CARRIES NO PARENTS AND NO IMAGE. The row is name, sex, age, derived birth year, date, place, spouse and film number - exactly the shape of [C.171], [C.172] and [C.173], his three sisters' entries, which this catalog has already recorded as carrying no parents. So the hope written on Ella (Sargent) Cooper that this record "would carry both parties' parents - which is the only route left to Enos Sargent" is closed: the index does not, and no image is served to check the return behind it. BUT ITS SUGGESTED-RECORDS PANEL DID THAT JOB INSTEAD - see suggested_records below. THE FILM IS A NEAR-NEIGHBOUR OF HIS SISTER'S. [C.173] (Matilda, 1896, Andover) is film 004211077; this is 004211081**. That bears on [C.173]'s todo t1, which judged an NJSA order cheaper than pulling three scattered reels (004209870, 004210073, 004211077) at a FamilySearch Center. A fourth return is now wanted, and two of the four sit four reels apart.
