Meagher is a County Tipperary surname, the anglicised form of the Gaelic Ó Meachair — "descendant of Meachar," a personal name connected to the Irish word for hospitable or generous. The Meaghers were a Gaelic sept whose territory sat in the political borderland between the O'Brien lords of Thomond and the Butler earls of Ormond, a landscape of rich farmland and medieval monasteries at the heart of Munster. Both Meagher and the alternate spelling Maher trace to the same Tipperary origin — Maher remains the more common form within Ireland, while Meagher became the standard spelling among the diaspora.
The name's most famous bearer is Thomas Francis Meagher, born in Waterford in 1823 to a merchant family of Tipperary descent. A leading voice of the Young Ireland movement, his 1846 speech defending armed resistance to oppression earned him the nickname "Meagher of the Sword" and, after the failed 1848 rising, a sentence of transportation to Tasmania. He escaped in 1852 and made his way to New York, where he became a prominent figure in Irish-American life. When the Civil War began, Meagher raised and led the Irish Brigade, whose service at Antietam, Fredericksburg, and Chancellorsville became legendary, before he went on to serve as acting Governor of Montana Territory until his death in 1867.
Cromwellian confiscation in the 1650s and later famine-era emigration pushed the Meagher name from Tipperary out into Britain, Australia, and above all the United States, where the Irish Brigade's fame gave it lasting resonance. This collection of tartan throw, garden flag, coasters, mug, license plate, t-shirt, and ornament honours that Tipperary-to-Montana story. Read the full account in our Meagher surname history.
