Genealogy sources for north Mayo families

North Mayo genealogy sources are not held in one place. A family in the barony of Tirawley can appear in Griffith’s Valuation, vanish from the parish baptismal register for a decade, and never once be named in a surviving workhouse record, because each of these repositories was built for a different administrative purpose and none of them was designed to track a single household across time.

Griffith’s Valuation and the barony of Tirawley

Griffith’s Valuation, the mid-century property survey conducted under Sir Richard Griffith, was published county by county rather than all at once. County Dublin came first, on 5 May 1853; County Mayo followed later, with the survey for the county completed on 13 July 1857, a decade after the worst famine years. The barony of Tirawley, which runs from the north Mayo coast down past Ballina, is nearly the second largest barony in the country and covers the civil parishes of Addergoole, Ardagh, Ballynahaglish, Ballysakeery, Crossmolina, Doonfeeny, Kilbelfad, Kilbride, Kilcummin, Kilfian, Killala, Lackan, Moygawnagh, Rathreagh, Templemurry, and part of Kilmoremoy.

The valuation lists occupiers by townland, not by household name alone, so a search has to start from a confirmed townland rather than a surname. Ask About Ireland hosts the full Tirawley printout free of charge, searchable by parish or barony. What Griffith’s cannot do is show change over time: for that, researchers move to the Valuation Office’s cancelled books, the manuscript ledgers that recorded amendments to each holding year by year after 1857. Those cancelled books survive for the Republic only at the Valuation Office in Dublin and are not digitised or searchable online, unlike the equivalent revision books for Northern Ireland, which the Public Record Office of Northern Ireland has put online in full.

Killala diocesan registers and their gaps

The Catholic Diocese of Killala covers the parishes of north Mayo, and its surviving registers were microfilmed by the National Library of Ireland and released as free digitised images in 2015. The coverage is uneven parish by parish. Killala parish itself has a baptismal register beginning only on 6 April 1852 and a marriage register beginning on 14 December 1873, both well after the mid-1840s. Kilmoremoy parish, which covers Ballina town, has an earlier run of baptisms from 1 May 1823, but that register breaks off on 14 October 1836 and does not resume in any continuous form until 23 July 1851, apart from a single fragment covering 9 May to 16 July 1849.

That gap in the Kilmoremoy register runs directly through the famine years. A birth, marriage, or death in that parish between late 1836 and mid-1851 has almost no chance of appearing in the surviving Catholic sacramental record, regardless of how carefully a family kept its own account of events. Researchers working the Killala diocesan registers for this period need to treat the absence of an entry as a limit of the record, not as evidence that a baptism or marriage did not take place.

Ballina Union workhouse records

The Ballina Poor Law Union was formed in 1840 and its workhouse, built to George Wilkinson’s standard design for the Poor Law Commissioners, was certified fit to admit paupers on 15 November 1842, with the first admissions recorded on 3 November 1843. It was designed to hold 1,200 inmates and became one of the largest workhouses in the country. The union’s 17 electoral divisions stretched across north Mayo and into south Sligo, taking in Ballina, Ballycastle, Killala, Kilfian, Lackan, Crossmolina, and Belmullet.

Surviving Ballina Union workhouse records, chiefly the Board of Guardians’ minute books, are held at the National Archives of Ireland, with further local material at the Local Studies department of Castlebar library. These are minute books rather than admission and discharge registers, so they record what the guardians decided and spent rather than a name-by-name account of who entered or left the workhouse. Some record series that identify individual paupers carry closure periods, so it is worth confirming access before a visit. The National Archives’ own national guide to Poor Law records highlights only a small number of unions, chiefly around Dublin, which means Ballina material has to be traced through Mayo-specific channels rather than a single national index.

Tithe Applotment Books before the valuation

The Tithe Applotment Books of 1823 to 1837 predate both Griffith’s Valuation and the surviving parish registers for most of north Mayo, and they cover the Tirawley civil parishes, including Kilmoremoy, Kilfian, Ballysakeery, Doonfeeny, and Lackan. Compiled to calculate payments to the Church of Ireland, they list the occupier of each townland holding and the acreage assessed, giving a picture of who held land roughly ten to twenty years before the famine. The National Archives of Ireland has digitised the full set and made it free to search by county, parish, and surname, with the original page images attached to each entry.

Used alongside Griffith’s Valuation for the same townland two decades later, the tithe books let a researcher see whether a family name persisted on a piece of ground through the intervening period, though neither source explains why a name disappears between the two.

The North Mayo Family Heritage Centre and civil records

The North Mayo Family Heritage Centre, based at Enniscoe near Castlehill outside Ballina, was founded in 1983 and is a member centre of the Irish Family History Foundation, which operates the RootsIreland.ie database. Its holdings include transcriptions from 31 Roman Catholic and ten Church of Ireland parishes, seven Presbyterian and six Methodist congregations, civil birth, marriage, and death records, and monumental inscriptions from 116 graveyards across the region. Civil registration in its own right generally begins in 1864 for Catholic marriages and general births and deaths, and from 1845 for non-Catholic marriages, so the civil record and the parish record overlap only from the mid-1860s onward.

Because the centre indexes registers that the National Library’s free digitisation does not cover in full, a search through RootsIreland can sometimes surface an entry, such as an Addergoole or Ballycastle baptism, that has no equivalent in the free online image collection for that parish.

What north Mayo genealogy sources cannot show

None of these repositories was built to follow one household across sources, so a family’s disappearance from a register rarely explains itself. A name missing from Griffith’s Valuation, absent from the tithe books twenty years earlier, and never entered in a workhouse minute book could mean emigration, a landholding recorded under a different family member, or simply a townland where the surviving record itself has a gap.

Emigration was not routinely recorded at all at parish or Poor Law level. No register in north Mayo notes that a son or daughter left for Boston, Liverpool, or elsewhere, and the 1836 to 1851 gap in the Kilmoremoy baptismal register means that an entire cohort born or married in that parish during the worst famine years left no sacramental trace whatsoever. Genealogy in north Mayo has to work from what several repositories independently confirm, never from the silence of one.

Readers following the wider county Mayo emigration history or researching the Ballina workhouse during Black ‘47 will find these record gaps sit inside the same famine years.
