Forstall Irish Surname History: Kilkenny, Variants & Records

Forstall is a rare Hiberno-Norman Irish surname rooted especially in County Kilkenny. Historical spellings include Forstal, Forestall, Forrestal, Forristal and Furestal. Surviving deeds place named Forstalls in Kilkenny by the early fifteenth century, while later records connect the family with land, mills and civic office around Shillelogher, Callan and Rosbercon.

The evidence supports a real Irish history, but it does not support treating every modern bearer as part of one proven pedigree. The safest approach is to use the surname's variants and Kilkenny geography as research leads, then build each family line from records.

What does the Forstall surname mean?

In Irish Names and Surnames (1923), Patrick Woulfe indexed the name under Fuireastal and listed forms including Furestal, Forestall, Forrestal and Forstall. He connected it with the medieval Latin forestarius: a forester or keeper of a forest. Woulfe described the family as Anglo-Norman, long established in County Kilkenny, with another presence in County Wexford.

That occupational explanation is useful, but surname etymology is rarely a complete family tree. Modern dictionary traditions also connect Forrestal with English place-names formed from Middle English elements. Those explanations are not necessarily mutually exclusive, and neither proves the ancestry of a particular Forstall household. Original spellings, locations and relationships matter more than a neat origin story.

Why is County Kilkenny central to Forstall history?

Kilkenny is not attached to the name by later family lore alone. National Library of Ireland manuscript catalogues preserve dated transactions involving Forstalls across the county.

1416: Patricia and Johanna Cantewell granted lands in Ballaghmichow, in Shillelogher, to Henry Forstall.
1593: Richard Forstall, described as sovereign of Callan, joined the burgesses in granting a castle and messuage in the borough.
1596: Thomas Forstall and Sir William Bargee granted a mill beside Rosbercon to Johan Shee.

These records do more than supply early dates. They show the name operating in several parts of Kilkenny society: landholding, borough government and the management or transfer of economically useful property. They also place Forstalls among other established southeast-Irish families, including the Cantwells and Shees.

The wider setting is explored in our histories of the Butler dynasty of Kilkenny and Ormond and the Hiberno-Norman Fitzgerald surname. These families were not interchangeable lineages, but their histories help explain the political and cultural world in which documented Forstalls lived.

Are Forstall, Forrestal and Forristal the same surname?

They can represent the same historical name, and a serious search should test all of them. Useful forms include:

Forstall and Forstal
Forrestal, Forrestall and Forestall
Forristal and Forristall
Furestal and similar phonetic spellings

However, a spelling match is a clue rather than proof. Forster and Forrester, for example, may sometimes appear in older surname lists beside Forstall, but they can also have independent histories. Before merging two people, check whether the parish, occupation, relatives, witnesses and land references agree.

How to trace a Forstall family line

Because the name is rare, location can be unusually valuable. Start with the most recent proven relative and work backward, recording every spelling exactly as it appears.

Establish the Irish place. Use civil certificates, census returns, passenger records, obituaries and family papers to identify a townland or parish.
Search the spelling cluster. Repeat searches for Forstall, Forstal, Forrestal and Forristal rather than relying on automatic variants.
Separate households. Compare occupations, spouses, children, sponsors and neighbouring families before joining records.
Move into local sources. Once a Kilkenny or Wexford parish is known, examine church registers, valuation material, wills, deeds and estate papers.
Treat published pedigrees cautiously. A documented medieval Forstall does not by itself establish descent for a modern family.

What about a Forstall crest or coat of arms?

Heraldic records may document arms for particular Forstall or related lines, but arms historically belonged to specific bearers and their legitimate successors—not automatically to everyone sharing the surname. A crest-style heritage design can celebrate the name, but it should not be treated as proof of personal entitlement or descent from a particular medieval branch.
