  Searched for: THE NEW JERSEY DEATH INDEX for the window the 1940 census had just defined. Collection 61260, "New Jersey, U.S., Death Index, 1848-1878, 1901-2017": (a) surname Maines, no given name, died 1929-1941; (b) THEN A COVERAGE CONTROL, because (a) looked wrong: surname Smith - the commonest surname in the state - with no given name and no place, died 1930-1932, then 1933-1937, then 1938-1948, then 1949-1951, then 1930-1952.

  Result: NOT A NULL - A NINETEEN-YEAR HOLE IN THE INDEX, AND IT SWALLOWS HER WHOLE. (a) 21 rows, every one dated 1929 and none of them her. (b) Smith returns ZERO for 1930-1932, ZERO for 1933-1937 and ZERO for 1938-1948, against 1,369 for 1949-1951 and a full set for 1929. Zero Smiths in a four-million-person state across nineteen years describes the COLLECTION, not the state. => Deaths of 1930-1948 are not in this index at all - and [D.882] plus the 1940 census put hers in 1930-1940. The one index that should have had her cannot reach the decade she died in. This search is therefore NOT evidence of absence and must not be re-run. Written up once, for the whole catalog, as guidance/reference_nj_death_index_1930_1948_gap.md. Note the collection's TITLE conceals this: "1848-1878, 1901-2017" reads as continuous.

  Searched for: NOT A NAME SEARCH - the two Andover Cemetery memorials of the household she was living in were PARSED with scripts/fetch_findagrave.ps1: 19511084 (Sarah Matilda (Cooper) Kinney Sarah Matilda (Cooper) Kinney, her daughter) and 19511070 (George R. Kinney George R. Kinney, her son-in-law, whose memorial this catalog had never parsed). Both are Andover Cemetery, plot Front Section. The question asked was whether a mother who died in her daughter's house is linked or buried with her.

  Result: SHE IS IN NEITHER FAMILY PANEL. Sarah Matilda's panel links her father Roderick Byanton Cooper Roderick Byanton Cooper, her husband, three siblings (Ida Elizabeth, Warren Edgar, Alfred) and one child; it does not link her mother. George's panel links his own parents (Horatio N. Kinney 1840-1909 and Elizabeth Ann Struble Kinney 1839-1889), two siblings and one child. No Rosetta, no Maines, no Mains, no Sickles anywhere in either. WHAT THAT IS AND IS NOT. It is NOT evidence she is not buried at Andover Cemetery - a panel records what a contributor linked, and Sarah's panel omits two of her own sons, so it is demonstrably incomplete. It IS a reason to search the cemetery itself rather than expect the family panel to deliver her. STILL TO DO: a located Find a Grave sweep for the surname MAINES (then Mains, then Cooper) in Sussex County with the locationId control-tested, and a look at the Andover Cemetery interment list. Four photographs across the two memorials have not been examined. THE LOCATED SWEEP WAS RUN THE SAME AFTERNOON - see the next row. The photographs are still unexamined.

  Searched for: THE LOCATED NAME SWEEP THE ROW ABOVE LEFT "STILL TO DO". Two searches on findagrave.com/memorial/search, surname only, no given name and no year range, so that nothing could be suppressed by a wrong date: (a) lastname=Maines, location Sussex County, New Jersey, USA, locationId=county_1925; (b) lastname=Mains, same location and id. EVERY ROW OF EVERY PAGE WAS READ - 56 Maines over three pages, 35 Mains over two. THE LOCATION FILTER WAS CONTROL-CHECKED AND IT HOLDS: all 91 rows name a Sussex County cemetery, so this is a filtered result and not merely a ranked one. (That check is not ceremonial - Find a Grave silently ignored the location filter on this file's own 2026-10-03 searches, and three Ancestry location ids were guessed wrong on 2026-10-25.)

  Result: NULL FOR HER, AND A SECOND NULL NOBODY HAD ASKED FOR. (1) No Rosetta, Rosette or Rozetta Maines or Mains in Sussex County - and no R-forenamed Maines/Mains woman of anything like her age. The nearest in year are Catherine B. Maines (1827-1904), Nancy B. Lyon Mains (1818-1875) and Margaret J. Jones Maines (1864-1940), none of them her. (2) NEITHER IS NELSON MAINS, her second husband - d. 1900, married her at Andover in December 1897. He is absent from both spellings. That is worth having: the family she married into is well represented in the county (91 memorials, concentrated at Newton, Vaughan, Sparta, Baleville and Tranquility), so his absence is not a thin-coverage artefact. Whatever happened to her burial record happened to his as well. WHAT THIS IS. A bounded null on the surname she died under, in the county she died in. It is NOT evidence she is not buried in Sussex County - about a third of burials have no memorial at all, and her FIRST husband Roderick Byanton Cooper lies at Tranquility with no gravestone ([G.512]) - but it does close the cheapest route to her death date. WHAT IS LEFT: the Andover Cemetery interment list itself (where her daughter and son-in-law lie, Front Section); the Sussex County Surrogate, untouched by the 1930-1948 death-index gap; and the two newspaper engines, which remain unrun for her. She was NOT searched here under Cooper or Sickles - she had been a Mains for thirty-odd years by then, and a Cooper sweep of Sussex County is a different, much larger search.

  Searched for: SHE COULD BE BURIED UNDER COOPER, MAINS OR SICKLES, so the sweep was run on the GIVEN NAME with the location filter bound and control-tested, which catches any married surname: (a) first name Rosetta, no surname, Sussex Co., NJ (locationId=county_1925), sorted by birth year - 25 memorials; (b) the same in Warren Co., NJ (county_1927) - 21 memorials; (c) surname Mains, Sussex Co., NJ - 35 memorials. The ids were taken from the site's own autocomplete and control-tested (Cooper in county_1925 returns 136 memorials, all in Sussex Co. cemeteries). (link)

  Result: NULL, AND IT IS AN ENUMERATED NULL, NOT A PAGE-1 SAMPLE. Sorted by birth date, the Sussex Rosettas run 1817, 1820, 1825, 1836, 1838, 1847, 1851, 1858, 1860, 1864, 1867, 1869, 1869, 1870, 1874, 1880, 1881, 1898, 1898, 1899 - NONE born in the 1840s but one (1847), and she is Rosetta Hough, dead at three months. Warren is the same shape: 1813, 1823, 1833, 1836, 1839, 1840, 1846, 1849, 1850, 1850, 1851, 1852, 1853, 1854, 1856, 1866, 1868, 1898, 1908 - the 1846 is Rosetta Mackey Boyd of Washington Cemetery, a Mackey who married a Boyd. No Rosetta Mains in Sussex at any date. SHE HAS NO MEMORIAL IN EITHER COUNTY. Note that her first husband is buried at Tranquility Cemetery with NO GRAVESTONE ([G.512]), so an unmarked grave in that plot is the obvious possibility and Find a Grave cannot see it.
