Searched for: THE NEW JERSEY DEATH INDEX FOR HIS WINDOW. Collection 61260 ("New Jersey, U.S., Death Index, 1848-1878, 1901-2017"): surname Cooper, no given name, no place, died 1912 +/- 6 (1906-1918) - 146 rows, all three pages read. Then four CONTROLS on Smith, surname only, no given name, no place, because the Cooper result looked wrong: died 1904-1908; died 1909-1915; died 1916-1918; and two boundary probes at 1902-1908 and 1901-1909.

Result: NO CALVIN COOPER - AND THE NULL IS WORTHLESS, BECAUSE THE INDEX DOES NOT COVER HIS YEARS. Every one of the 146 Cooper rows is dated 1916, 1917 or 1918; not one falls in 1906-1915. THE CONTROL SETTLES IT. Smith - the commonest surname in the state - returns zero for 1904-1908, zero for 1909-1915, and 1,376 for 1916-1918. The boundary probes show 1901 and 1902 ARE covered. => Collection 61260 has a second coverage hole, c.1903-1915, in addition to the 1930-1948 one found earlier the same day. Written up as the second half of [[reference_nj_death_index_1930_1948_gap]]. His entire disappearance window sits inside it, so this engine can never answer the question. Routes that remain are on todo t1.

Searched for: TWO SEARCHES ON findagrave.com/memorial/search, EVERY ROW OF BOTH READ. (a) The located county sweep, by surname only - lastname=Cooper, no given name, location Sussex County, New Jersey, locationId=county_1925, died 1912 +/- 6 (so 1906-1918, which brackets his whole disappearance window and then some). 14 rows, all read. (b) The name sweep, unlocated - firstname=Calvin, lastname=Cooper, born 1906 +/- 4 (1902-1910), no location and no death year, so nothing could be suppressed by a wrong date or a wrong place. 40 rows over two pages, EVERY ONE READ.

Result: A BOUNDED NULL ON BOTH SIDES, AND THE LOCATION FILTER WAS CONTROL-CHECKED. (a) All 14 Sussex County Coopers of 1906-1918 are ADULTS - Amanda J. Batley (1838-1915), Andrew J. (1855-1911), Caleb S. (1834-1913), Catherine Dennis (1832-1917), Clara Slaughter (1888-1916), Edward (1875-1914), Effie May (d. 1918), Esther Clock (d. 1918), James Manning (1855-1912), John P. (1853-1915), Manning (1857-1912), Rachael (1832-1914), Sylvester (1845-1912) and Thomas (d. Aug 1909). There is no child's memorial among them and no Calvin. Every one of the 14 names a Sussex County cemetery - Tranquility, Newton, North Hardyston, Glenwood - so this is a FILTERED result and not merely a ranked one. (b) NOT ONE of the 40 Calvin Coopers born 1902-1910 is in New Jersey. They are in Ohio, Louisiana, South Dakota, Michigan, Florida, Ontario, Arkansas, Virginia, California, Idaho, Texas, Minnesota, Tennessee, Maryland, Iowa, Illinois, Mississippi, West Virginia, Montana, Kentucky, South Carolina, Alabama and Kansas. Most lived into the 1960s-1990s. ONE IS WORTH NAMING AND IT IS NOT HIM: Walter Calvin Cooper, 26 Aug 1907 - 31 Aug 2000, Peace Creek Cemetery, STAFFORD, KANSAS. Stafford is where this catalog's Levi branch settled - Levi H. Cooper's descendants, the other side of John Cooper's tree - so a Calvin recurring there as a middle name is a coincidence worth noticing and nothing more. He was born in Kansas and our Calvin was in Andover, New Jersey, aged four, in April 1910. => This closes the cheapest remaining route on todo t1. It is NOT evidence he has no grave - about a third of burials carry no memorial, and his own grandfather Roderick Byanton Cooper lies at Tranquility with no stone at all ([G.512]) - but the family plot and the county are now swept by name, and he is not in them.

Searched for: NOT a name search for him - a HOUSEHOLD search. Ancestry collection 61558 (New Jersey, U.S., State Census, 1915), surname Cooper with no given name, residence Andover, Sussex County; then the Albert A. Cooper record (2248509) opened, its image downloaded and all five lines of dwelling 108 read on census_stitch stitches = [E.40]. The question asked was simply whether he is in his parents' household in June 1915, at about nine years old.

Result: NOT THERE. The household is five people - Albert A. (Sept 1875), Sadie A. (Aug 1884), Albert S. (Dec 1902), Alvin G. (Sept 1909) and Violet M. (Apr 1913) - and he is not among them. His disappearance is now bounded between 15 April 1910 ([D.885], aged 4) and 1 June 1915. The search also returned the whole Andover Cooper set for 1915 and no Calvin Cooper of any age appears anywhere in it, in either Andover Borough or Andover Township. THIS IS NOT A DEATH RECORD AND IS NOT RECORDED AS ONE. It is an absence from one household in one enumeration.

Searched for: IS HE ANYWHERE IN 1920, AS SOMEBODY ELSE'S LODGER? The question comes from the pattern recorded on Myrtle E. (Cooper) Current and Adolph Stephen Cooper: two of Warren Edgar Cooper's children vanished from their own county's index as single adults and the lesson written there was to look for them as LODGERS and SERVANTS in other people's households rather than as heads. He would be about 14 in 1920. Collection 6061 (1920 United States Federal Census), three searches: (a) given Calvin, surname Cooper, birth 1906 +/- 2, no place - 45 rows, ALL READ; (b) given Calvin, surname Cooper, both marked EXACT, no birth year, no place - 86 rows, of which the FIRST 50 WERE READ; (c) the same exact-name search with birth year 1906 - zero.

Result: NOT FOUND, AND THE NULL IS HONEST ABOUT ITS OWN EDGES. (a) Not one of the 45 is actually named Calvin - every row is a C-initial match (C Kinsey, C K, Milford C, O C Jr, Leatha C, John C, A C, Horner C, C Hansel, C Frederick, C B, C Edward...), and none is in New Jersey. (b) Of the 50 exact Calvin Cooper rows read, exactly ONE is in New Jersey: a roomer at Jersey City Ward 8, Hudson Co., born about 1860 - aged sixty, and not him. 36 OF THE 86 WERE NOT READ, because &page=2 on this URL form silently returned page 1 again. That is recorded rather than glossed: this is a null over 50 of 86 rows, not over 86. (c) Zero for birth year exactly 1906 - but that is Ancestry matching the YEAR exactly too, and (b) shows Calvin Coopers born 1904, 1908 and 1911 do exist, so (c) says almost nothing and is recorded only so nobody re-runs it expecting more.

Searched for: A FAILED ATTEMPT, RECORDED AS ONE RATHER THAN AS A NULL. Three tries at an all-collections search filtered to New Jersey, using a guessed numeric place id in the URL: birth=1906_new-jersey-usa_40, then _new+jersey-usa_32, then residence=_new+jersey-usa_31.

Result: ALL THREE SILENTLY RESOLVED TO A DIFFERENT STATE, AND THE RESULTS ARE WORTHLESS. The URL Ancestry returned read oregon-usa_40, then new+hampshire-usa_32, then nevada-usa_31. The page gives no warning; it simply searches Oregon, New Hampshire or Nevada and returns a full, plausible result set. => NOTHING WAS LEARNED FROM THESE THREE AND NO NULL IS CLAIMED FROM THEM. The searches above that ARE recorded as nulls were run without any location filter, for exactly this reason, and read row by row instead. THE RULE THIS CONFIRMS: the only place ids this catalog should use are ones it has control-checked on a returned URL - e.g. _sussex-new+jersey-usa_2837, verified earlier the same day on Adolph Stephen Cooper. A guessed id is not a filter, it is a different search.
