The reputation comes from a real event: in 1922, the Public Record Office at Dublin's Four Courts burned, taking most of Ireland's nineteenth-century censuses with it. What the reputation misses is how much survived — and how much was reconstructed from other sources. Irish research is less about a single wall than about knowing the workarounds.

What survives

  • Civil registration — all births, marriages, and deaths from 1864 (non-Catholic marriages from 1845).
  • Catholic parish registers — baptisms and marriages, most beginning between the 1780s and 1820s, earlier in some towns; Church of Ireland registers where they escaped the fire.
  • Griffith's Valuation (1847–1864) — a property survey of nearly every household in Ireland, the great census substitute.
  • Tithe Applotment Books (1820s–30s) — earlier lists of landholders, parish by parish.
  • The 1901 and 1911 censuses — complete, and free to search.

The key is the townland

Irish records organize by townland — small, named patches of land, tens of thousands of them. "My family came from County Cork" starts a search; a townland name finishes it. Much of our work on Irish lines is precisely this: using American records — immigration manifests, naturalizations, church records, obituaries — to recover the townland, which then unlocks the Irish records themselves. Famine-era emigrants left thinner trails, and we're honest about where the record goes quiet.

How far back can an Irish line go?

For most Catholic families, the parish registers set the limit — typically the late 1700s to early 1800s. Anglo-Irish and landed lines can sometimes be followed considerably further. The free assessment will tell you what's realistic for your family before you commit to anything.

Sapling.Family is a family-history research service led by Professor Cisco Bradley, a historian at Pratt Institute. Every project begins with a free assessment — we look at what records exist for your family and tell you honestly what can be traced, before you decide anything.
