[2][3] Gaultier barony is derived from the Irish for "land of the foreigners" — specifically, the Vikings, who settled here when they were expelled from Waterford City by the Cambro-Norman and English invaders in the later 12th century.

It contained the parish of Kilculliheen until 1872, when that area was transferred to County Kilkenny.

Gaultier, as stated above, was a settlement of Vikings expelled from Waterford city.

[5] Other important families were Anthony, Brunnock, Comerford, Everard, Grant, Jackson, Mandeville, Sherlock, Wadding and Wyse.

[7] It gives its name to Gaultier GAA, a Gaelic football club established in 1927 and based in Dunmore East.
