Thomas Francis Meagher's[2] family line can be traced to second century AD. Ancestors had been Kings of Munster in the time of Con of the Hundred Battles.

Thomas's mother, Alicia Quan (1798–1827), was the second eldest daughter of Thomas Quan and Alicia Forristall. She died when he was three and a half years old. Thomas had four siblings; a brother and three sisters. Of his siblings, only his older sister Christine Mary lived past childhood. He was brought up by his elderly father and wealthy maiden aunt.

Thomas was an Irish nationalist and leader of the Young Irelanders in the Rebellion of 1848. After being convicted of sedition, he was first sentenced to death, but received transportation for life to Van Diemen's Land in Australia.

On February 22, 1851 Meagher married Katherine Bennett ("Bennie"). Katherine was the daughter of Bryan Bennett, a convicted highwayman.

In 1852 he escaped and made his way to the United States, where he settled in New York City.

His wife Catherine died in Ireland in 1854 after giving birth to a son. In 1856 he married Elizabeth Townsend, the daughter of Peter Townsend and Caroline (née) Parish of Monroe, New York, after Elizabeth converted to Catholicism.


Fell overboard from an Army steamboat in the Missouri River on July 1, 1867. His body was not recovered. He is remembered by the Irish Brigade Monument at Bloody Land memorial at Antietam National Battlefield at Sharpsburg, Maryland.[3]

There is a cenotaph at Green-Wood Cemetery, Brooklyn.

Shortly after, a petrified man found downriver from Fort Benton, Montana, was claimed by promoters to be his remains. The petrified man was displayed across Montana as a novelty and even exhibited in New York and Chicago.[4]


  • Meagher County, Montana is named in his honor.
