The D'Arcy Archive
17 holdings measured · 13 September 2026

What the indexes actually hold

Most of what this archive has failed to find, it failed to find in places that were never transcribed. This page is the measurement, kept separately because it is the difference between a null result and an empty search.

Read this first. Added 13 September 2026, after the fact. Every holding measured on this page is a FREE index, and on the day this page was built a subscription site was opened for the first time. It immediately produced the 1851 census household the archive had twice reported missing, the marriage it had never found, and the stretch of the Berkeley register it had called untestable. The measuring was right. The conclusion quietly drawn from it — that a record not reachable here did not exist in reach — was a statement about a budget.What it produced →

A free index is not a record office. Every one of them is a partial transcript of somebody else's volunteering, and the only honest way to use one is to find out what it holds before you report what it does not.

The method is a control test. The test is always the same: run a name that MUST be there through the same query that returned nothing. If the control comes back empty too, the silence belongs to the index.

Of the 17 holdings measured here, 8 turned out to be partial, empty or unreachable — and in every one of those cases this archive had already run a search against them and would have reported the emptiness as a fact.

Measured, not assumed

Ten holdings

This archive's own alias list The spelling of a surname

Holds: eleven forms of Saniger, when nineteen were needed

Test — Two records found within an hour of each other under spellings not on the list: SANIGOR (Hannah's baptism) and SANIGRE (her brother's marriage).

Every “not found” published here for this family was really “not found under the spellings I happened to think of”. The list now carries nineteen, and the failure was mine rather than any source's. Where it bites →

British Newspaper Archive England, Ireland, Scotland and Wales, 1790–1870

Holds: deeply, and it has been the most productive source of the fortnight

Test — Control on “Chatham”, May–December 1827: 4,733 articles. Date filters work once driven through the interface rather than the URL.

It produced Robert D'Arcy's seventeen death notices and his funeral, George Pitt D'Arcy's marriage and the only statement of his paternity, Joseph D'Arcy's obituary and his wife's name, and the Irish service of the 39th. None of that is in any parish register or census. Where it bites →

Free indexes, all of them The whole of this table

Holds: less than the record offices do

Test — FindMyPast, opened once. The 1851 Wakefield household, the 1831 marriage, and Berkeley baptisms 1792–1821 with parents named — all previously reported here as absent or untestable.

The commonest reason a record could not be found by this archive is that it was behind a subscription. Read every null below with that in front of it. Where it bites →

FindMyPast Berkeley St Mary the Virgin, baptisms

Holds: one partial index and no other

Test — HANNAH SMITH at Berkeley 1795–1815: nineteen results, and the only baptism collection returning anything for Berkeley is England Births & Baptisms 1538-1975, the FamilySearch index. FindMyPast's own Gloucestershire Baptisms covers Bristol parishes and does not reach Berkeley.

It is enough to put six Saniger generations on record. It is not enough to find Hannah, whose brothers of 1801, 1803 and 1808 are in it and who is not. Gloucestershire's parish registers are an Ancestry collection. Where it bites →

Every Irish marriage index reachable County Wicklow and Dublin diocese, 1813–1825

Holds: Roman Catholic parish registers, and nothing Anglican

Test — SMITH, marrying in Co. Wicklow 1813–1825: twenty-five results from exactly two collections — Ireland Roman Catholic Parish Marriages and Betham's Genealogical Abstracts. Seventy D'Arcy marriages across Dublin diocese 1814–1824, every one Roman Catholic.

An officer of a British line regiment married in the Church of Ireland, and those registers are the ones destroyed when the Public Record Office of Ireland burned in June 1922. This is the only holding on this page where the records are not merely unreached but gone. Where it bites →

British Newspaper Archive England, Ireland and Scotland, 1827

Holds: richly — and its date filters cannot be driven from a URL

Test — A control on the word “Chatham” for May–December 1827 returns 4,733 articles.

Seventeen notices of Robert D'Arcy's death were found once the filters were set by hand. The archive is deep; the obstacle was an interface, and this is the only holding on this page where the limit was mine rather than the source's. Where it bites →

FindMyPast South Leith, Midlothian

Holds: baptisms from the sixteenth century, with parents named

Test — One search. Jean Ward, 19 July 1754, father Joseph Ward, mother Martha Garden.

This archive reported South Leith as untranscribed and her baptism as unreachable, more than once and on more than one page. It was a statement about the free indexes and it was published as a statement about the parish. Where it bites →

FreeREG Berkeley St Mary, Gloucestershire

Holds: to 1677 only

Test — The transcript's own end date.

One of the six Saniger generations in the tree can be tested here. The other five — 1679, 1711, 1744, 1769, 1805 — fall entirely outside it. Where it bites →

FreeREG Portsea St Mary, Hampshire

Holds: baptisms, 1780 and 1781

Test — Five common surnames across Hampshire 1778–1783: 46 Portsea entries, all baptisms — 20 in 1780, 25 in 1781, one in 1782, none in 1778, 1779 or 1783.

Joseph D'Arcy's baptism survives inside a twenty-two-month window. The absence of his brothers and sisters proves nothing whatever. Where it bites →

FreeREG The city of Bristol

Holds: essentially nothing, 1800–1820

Test — William and Mary Smith across Gloucestershire 1800–1820: 289 entries from 75 parishes, and exactly ONE inside Bristol — a single entry at Stapleton.

St Paul, St Philip and Jacob, St James, Clifton, Bedminster, Temple, St Mary Redcliffe: absent at any size. Every Bristol search this archive has run was searching a city that is not in the index. Where it bites →

FreeREG Chew Magna, Somerset

Holds: a fragment

Test — Three forenames of Smith across Somerset 1795–1815: 943 entries from over a hundred parishes, and TWO from Chew Magna, against a hundred at Walcot and sixty-nine at Bath.

The parish that now carries the best lead on Hannah Saniger's birthplace cannot be searched from a desk. Where it bites →

FreeREG Oswestry, Shropshire

Holds: nothing

Test — Smith across Shropshire 1783–1792: 167 entries from the county — Shrewsbury 70, Hodnet 15, Ludlow 10 — and NONE at Oswestry.

Elizabeth Margaret Oliver's baptism, which the tree puts at Oswestry on 7 May 1787, cannot be tested here. Where it bites →

FreeREG Audlem, Cheshire — and Cheshire generally

Holds: almost nothing, 1800–1820

Test — John Smith across the WHOLE COUNTY 1800–1820 returns TWO entries — one at Whitegate, one at Wrenbury.

The marriage of Samuel Sneyd and Elizabeth Oliver at Audlem on 22 October 1809 cannot be tested here. This is the emptiest county holding this archive has measured. Where it bites →

FreeCEN Staffordshire

Holds: 1861 only

Test — John Smith born Staffordshire 1800–1805: 31 people, every one of them 1861.

Samuel Sneyd died in 1855 and his son had been in Australia since 1832. Neither was ever findable here, however hard anyone looked. Where it bites →

FreeCEN Gloucestershire and Somerset

Holds: 1841 through 1901, and richly

Test — William Smith born Gloucestershire 1800–1812 returns entries from 1841, 1851, 1861, 1871, 1881 and 1891, including twelve inside Bristol for 1851 alone.

This is why the census, not the parish register, is what has actually moved this archive's Bristol work. The Saniger household at Oxford Road came from here. Where it bites →

FreeBMD England and Wales, deaths, 1854–1863

Holds: complete enough to argue from

Test — Every Samuel Sneyd death registered in five years: exactly one. Every Elizabeth Sneyd in four: two, one of them at Stoke.

Strong enough that a single result across a five-year window can correct a family tree by a year. Used that way here. Where it bites →

Cloudflare CWGC · NSW BDM · irishgenealogy.ie · newspapers.library.wales

Holds: unknown

Test — None possible. Each sits behind a bot check that this archive will not attempt to defeat.

Four sources that may hold answers and that have never been read. They are on the errand list for a person with a browser, not recorded as nulls. Where it bites →

The pattern, and why it matters more than any one entry

Six of the ten holdings below are parishes or counties the FAMILY TREE NAMES, and again and again the exact places a claim points at are the places the free indexes have not reached. But the sharpest lesson came last and from a different direction. A control test proves that a source covers a parish and a window. It proves NOTHING about whether your search string can reach the record. Hannah Saniger's baptism was declared missing twice, each time behind a sound control test, and it was sitting in an index this archive had already searched — under SANIGOR, one of the very few spellings the alias list did not carry. Her brother's marriage was hidden the same way, under SANIGRE. Widen the name before you narrow the conclusion.

This is the rule the rest of the site is supposed to follow. Before reporting that something is not there, establish that the source covers the parish and the window. The two times this archive has broken that rule it produced published errors — a two-year transcript read as a searched parish, and an untranscribed city read as an empty one — and both are on the errors page rather than quietly fixed.
This page, measured against itself

Twice the instrument was the thing at fault

A page that measures other people's indexes should be read the same way, and twice it has failed its own test. Both faults were in the instrument rather than in any source, and both would have been invisible to a reader.

15 September 2026 A verdict displayed as something it did not mean

The template that renders this table was a fallthrough chain — good, partial, absent, and everything else «cannot answer». So blocked, which means a source nobody has asked, because it wants an account this archive will not make, displayed as a source that had been asked and could not answer. Those are opposite statements: one is about this archive's choice and the other about the source's emptiness. One row also carried the freehand verdict «unusable as a control», which fell through the same way. The five words are now declared in the data, the template looks them up instead of falling through, and a gate refuses any verdict outside the list.

27 September 2026 A zero that belonged to the question, not the archive

Trove's title endpoint returns its gazettes under the key newspaper. Asking it for a gazette key returns nothing, so the first run of the script that measures Australian holdings reported 0 gazettes — and that was one commit from being published as a fact about Trove. It is a fact about the parser. The endpoint's own total is now compared with what the parser found and a disagreement refuses the build: newspaper 2,014 = total 2,014, gazette 38 = total 38.

Both belong here rather than on the errors page alone, because a reader deciding how much to trust the verdicts above is entitled to know that the verdicts have twice been wrong for reasons that had nothing to do with the records. Every error, kept →
