Six years in the wrong province, then one week

What we had to start with

One line in a Latin marriage register at Alton, Illinois, 1878: William Wiley, son of William Wiley and Margaret Flynn. That was the whole Irish inheritance. No county, no parish, no ship, no grave for the parents. William II's own records said only “Ireland”. Wiley is not a rare name and Flynn is a very common one.

The family tree also carried a lead: a Margaret Flynn baptised at Kilfinane in the south of County Limerick on 19 January 1835. It had arrived as a database hint, matched on the name and a rough birth year, and over time it hardened into a fact. Her “born 1835” in the tree was that hint's date.

Six years in Munster

Because the only Irish document in hand was about the wife, the husband was hunted where the wife's record was. Chris read the Catholic registers of Kilfinane, then Fethard and Cahir in Tipperary, page by page at high magnification, some 1,500 image reads over six years, looking for a William Wiley marrying a Margaret Flynn between 1850 and 1855 or a William baptised in 1855 to 1857. There were Wileys in Tipperary, but not ours. Every negative was logged. The registers were eliminated at the level of the record, which is the standard that made the later change of direction defensible rather than a mood.

The measurement that changed direction

In August 2026 two simple counts were made that should have been made at the start. First, in Griffith's Valuation, the mid-century survey of every landholder in Ireland, there are about 450 Wiley households in Ulster and 9 in the whole of Munster, with none at all in County Limerick. Wiley is a Scots name that came to Ireland with the Ulster plantations. Second, civil registration of non-Catholic marriages began in Ireland in 1845, and the index holds no William Wiley marrying a Margaret Flynn anywhere; so the marriage was Catholic, which is why no state index had ever produced it. The search moved north, to a parish on the Monaghan–Fermanagh border where Wileys and Flynns lived side by side and a “Joanna Wily, converted from Protestantism” had married a Catholic. That turned out to be wrong too. But it broke the six-year habit of looking in the south, and it put the right question on the table: a Catholic Wiley family is unusual, so where did one live?

The DNA, in plain words

On 29 and 30 August 2026 Dad's match list was sorted into families. One stood out: six related people, Kennys and Newmans and one tester known only as “catimf”, who all match Dad, all match each other closely, all match the documented descendants of William II's other children, and match none of the eighteen testers known to descend from the German Giese side. That pattern places their connection above William II and Alice, on the Irish or the English side.

Thomas Kenny's family tree had, on his grandmother's side, a woman recorded as “M Wiley Brady Byrne”, born 1843 at “Cullintry, Rathmolyon, Co. Meath”, died 30 January 1886 at Clonard, wife of James Byrne, mother of Catherine Byrne who married a Kenny and died in Chicago in 1973. On WikiTree, out of 43 million profiles, she was the only Wiley born in Meath. Chicago was the city William II's death notice had asked to copy, unexplained for a century. Meath had never once been considered.

One civil record, the same night

Irish civil registration of Catholic marriages began in 1864 and the records are free online. Within the hour Chris had the Trim district marriage of 4 July 1881: James Byrne, widower, publican, of Clonard, married Grace Brady formerly Weily, widow, of Cullentry, daughter of William Weily, farmer, deceased; witness Jane Flynn. Every piece of the garbled tree entry was explained (Grace not Margaret; Brady her first married name), and both brick-wall surnames stood in one record from south-west Meath. The dangerous alternative reading, “Reily”, was ruled out at zoom against the same clerk's W's and R's on the same page.

Two checks followed. Cullentry is a real townland, the only one of its name in Meath, in Rathmolyon civil parish, according to the national placenames database. And the Catholic chapel that served it, Longwood (also called Killine), has a surviving register of 158 images running from 1829 to 1878, which nobody had ever opened for a Wiley.

The register

On 5 September 2026 the Longwood register was fetched from the National Library and read in its entirety, with the help of an AI research assistant that could work through the images page by page and enlarge every candidate name against control letters on the same page. The book is in English and clearly written. It yielded exactly five Weily entries between 1833 and 1878 (the 1839 and 1842 baptisms, Grace as sponsor in 1853, the 1854 remarriage, Grace's 1876 wedding) and four more for Michael Wiley and Anne Daly in the 1870s. It also yielded the negatives that shape the story: no Weily marriage in 45 years, no Weily child between 1833 and 1838, no William baptised in early 1857, no Weily death to 1855. And the National Library's list showed that Cullentry's own parish, Rathmolyon, has no register before 1878. The lost book is where our William was baptised and married.

Griffith's, the landlord's papers, the map, the tithe book

The same day, Griffith's Valuation put William, Margaret and Ellen Wiley on three adjacent lots at Cullentry in 1854. That evening Chris found, in the National Library's catalogue, the estate papers of the family's own landlords, the Fowler and Rawdon of Rathmoylon Papers: leases of Cullentry to William Wiely in 1835, John Wielly and John Wiely in 1835, Ellen Weily in 1841 and John Weilly in 1861, with yearly rent books from 1837 to 1867. He noticed that a lease “for 2 lives or 21 years” from 1 January 1835 ends on 1 January 1856, and that William II arrived in America in 1857.

Late that night he found the Longfield estate map, fetched it at full resolution from the Library's image server, and there was Robert Weily at Heghlane in the 1770s, with five later Wyleys written over his farm and the Flynns two farms away along the road to Longwood. The next day the 1825 tithe book confirmed the farm's name, Heghlane, and put William Senior, William Junior and Michael on it.

Why we believe it

Not because of any one document. Because five independent kinds of evidence, made by five different sets of people for five different purposes, agree on one farm:

1. A state record (1881) naming a William Weily, farmer, of Cullentry, with a Flynn witness.
2. A parish register (1839 to 1876) with a William Weilly married to a Margaret Flynn, in the only Weily family in the book.
3. The landlord's own leases and rent books (1835 to 1861) with the family's own spelling of the name and a lease that ran out the year before the crossing.
4. A surveyor's map (1770s to 1790s) and a tax book (1825) putting the family on the same named farm for eighty years before that.
5. The DNA of six living people descended from Grace Weily of that farm, matching Dad and his brother at the expected amounts and attaching to the Irish side of the family by elimination.

What we do not have is a document naming our William as a child of that house, and we say so on the open questions page. The next documents to arrive, the 1835 lease and the rent books, are the ones most likely to supply it.

What went wrong, honestly

• A database hint was allowed to become a fact. Margaret Flynn's Limerick baptism was never more than a name-and-year match, and it steered six years of work.
• The husband was searched where the wife's record was. The Wiley surname's own geography, which pointed away from Munster, was not measured until 2026.
• Leinster was never counted. When Ulster and Munster were compared, the middle of the country was left out, and that is where the family was.
• The Kilfinane lead is retired to “Possible” at most. It would revive only if an American record for Margaret Flynn Wiley named her parents as Thomas Flynn and a Clanchy or Clohessy.
