James Knox Polk (Scotch-Irish)

11th President, 1845–49: His ancestors were among the first Ulster-Scots settlers, emigrating from Coleraine in 1680 to become a powerful political family in Mecklenburg County, North Carolina. He moved to Tennessee and became its governor before winning the presidency.[74]

James Buchanan (Scotch-Irish)

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". The Buchanans were originally from Deroran, near Omagh in County Tyrone where the ancestral home still stands.[74] Buchanan also had pre-plantation Irish ancestry being a descendant of the O'Kanes from County Londonderry.

Andrew Johnson (Scotch-Irish & English)

17th President, 1865–69: His grandfather left Mounthill, near Larne in County Antrim around 1750 and settled in North Carolina.

23rd President, 1889–93: His mother, Elizabeth Irwin, had Ulster-Scots roots through her two great-grandfathers, James Irwin and William McDowell.

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. His second term as president was cut short by an assassin's bullet.[74][79]

Theodore Roosevelt (Scotch-Irish, Dutch, Scotch, English & French)

26th President, 1901-09: His mother, Mittie Bulloch, had Ulster Scots ancestors who emigrated from Glenoe, County Antrim, in May 1729. Roosevelt praised "Irish Presbyterians" as "a bold and hardy race."[80] 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."[81] (*Roosevelt was referring to "nativists", not American Indians, in this context)[82]

William Howard Taft (Scotch-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.[89][90]
