Presidents

At least 22 presidents of the United States have some Irish ancestral origins,[89] although the extent of this varies. For instance, President Clinton claims Irish ancestry despite there being no documentation of any of his ancestors coming from Ireland, while Kennedy has strongly documented Irish origins. Ronald Reagan's great-grandfather was an Irish Roman Catholic. Kennedy and Joe Biden were raised as practicing Catholics.

  • 15th President, 1857–61: Born in a log cabin (which has been relocated to his old school in Mercersburg, Pennsylvania), 'Old Buck' cherished his origins: "My Ulster blood is a priceless heritage".

    Andrew Johnson (Irish & English)
  • 17th President, 1865–69: His grandfather suppoosedly left Mounthill, near Larne in County Antrim around 1750 and settled in North Carolina he was of English ancestry.

    William McKinley (Scotch-Irish & English)
  • 25th President, 1897–1901: Born in Ohio, the descendant of a farmer from Conagher, near Ballymoney, County Antrim, he was proud of his ancestry and addressed one of the national Scotch-Irish congresses held in the late 19th century.

Roosevelt praised "Irish Presbyterians" as "a bold and hardy race."[102] However, he is also the man who said: "But a hyphenated American is not an American at all. This is just as true of the man who puts "native"* before the hyphen as of the man who puts German or Irish or English or French before the hyphen."[103] (*Roosevelt was referring to "nativists", not American Indians, in this context)[104]

    George H. W. Bush (Irish & English)
  • 41st President 1989–93: County Wexford historians have found that his now apparent ancestor, Richard de Clare, Earl of Pembroke (known as Strongbow for his arrow skills) – is remembered as a desperate, land-grabbing warlord whose calamitous foreign adventure led to the suffering of generations. Shunned by Henry II, he offered his services as a mercenary in the 12th-century invasion of Wexford in exchange for power and land. He would die from a festering ulcer in his foot, which his enemies said was the revenge of Irish saints whose shrines he had violated. The genetic line can also be traced to Dermot MacMurrough, the Gaelic king of Leinster reviled in history books as the man who sold Ireland by inviting Strongbow's invasion to save himself from a local feud.[111] [112]
    Bill Clinton (Irish, Scotch-Irish & English)[113]

    Barack Obama (Kenyan, English & Irish)
  • 44th President 2009–2017: His paternal ancestors came to America from Kenya and his maternal ancestors came to America from England. His ancestors lived in New England and the South and by the 1800s most were in the Midwest. His father was Kenyan and the first of his family to leave Africa.[115] [116] His great great grandfather, Falmouth Kearney, was born in the Irish town of Moneygall.[117]
    Joe Biden (Irish and English)
  • 46th President 2021-present: His closest link to Ireland is his great-grandfather James Finnegan, who was born in County Louth, Ireland in 1840.[118]
