Of the 44 men who have become president of the United States, 22 can trace some of their ancestry to Ireland. So as the nearly 33 million Americans of Irish descent prepare to celebrate St. Patrick’s Day, 24/7 Tempo has compiled a list of those with Irish ancestry who have served as president.

Starting with Andrew Jackson, who became president in 1829, most of the country’s chief executives with Irish lineage came from Ireland’s northern counties of Tyrone and Antrim. All were Protestant and identified as Scots-Irish to distinguish themselves from the Catholics living in the southern part of the island. Here is each president’s path to the Oval Office.

It wasn’t until John F. Kennedy — the most Irish of all the American chief executives — became the first Catholic elected as president in 1960 that any president of Irish extraction made his ethnicity a point of pride. Kennedy’s visit to Ireland in June of 1963 prompted an enthusiastic reaction and he vowed to return to his ancestral home. That never happened. He was assassinated five months later at age 46, one of the youngest presidents to die in office. Here is how long American presidents live.

Since Kennedy’s election, other presidents have used their Irish connections to mine the votes of Irish Americans. Some presidents with Irish ancestry have journeyed to the Emerald Isle while in office, among them Richard Nixon (1970), Ronald Reagan (1984), and Barack Obama (2011). Even though Bill Clinton’s Irish connection has not been fully verified, the 42nd president was a staunch proponent of the peace process in Northern Ireland. He visited the island three times as president.

24/7 Tempo compiled its list of U.S. presidents with Irish heritage by reviewing websites such as ulsterscotsagency.com, academica.edu, irishcentral.com, https://www.bbc.com, and whitehouse.gov. As many as 25  presidents supposedly claim Irish ancestry. However, three of them — William Henry Harrison, Abraham Lincoln, and Bill Clinton — do not have fully corroborated evidence of Irish heritage. Our list is composed of presidents with the most verifiable claims to Irish ancestry.

1. Andrew Jackson (1767-1845)
> Birthplace: Waxhaws region, South Carolina
> Party: Democrat
> Term: 1829-37 (7th president)

Andrew Jackson was born in the Waxhaws region of South Carolina, two years after his parents left the village of Boneybefore, in County Antrim in the northern part of Ireland. The seventh president was a hero during the War of 1812 and helped found the Democratic Party.

2. James Polk (1795-1849)
> Birthplace: Mecklenburg County, North Carolina
> Party: Democrat
> Term: 1845-49 (11th president)

The 11th president traced his Irish lineage to his great-grandfather Robert Bruce Polk, who was born in Scotland and lived in Lifford in County Donegal, in the province of Ulster, before coming to Maryland in 1680, and then moving to North Carolina. The United States expanded west and southwest during Polk’s presidency, eventually adding Texas and California as states, and territories in the Southwest that would become the states of New Mexico and Arizona. The country also fixed its current border with Canada through negotiations with Great Britain.

3. James Buchanan (1791-1868)
> Birthplace: Cove Gap, Pennsylvania
> Party: Democrat
> Term: 1857-61 (15th president)

James Buchanan, the last president to serve the United States before the Civil War, had grandparents who came from The Cairn, Ramelton, in County Donegal. Buchanan considered the issue of slavery a states’ rights issue. He also said that while states had no right to secede, the federal government did not have the right to intervene either.

4. Andrew Johnson (1808-1875)
> Birthplace: Raleigh, North Carolina
> Party: Democrat
> Term: 1865-69 (17th president)

Andrew Johnson, who became president after Abraham Lincoln was assassinated, traced his Irish roots to the village of Mounthill in County Antrim. His grandfather left Mounthill in 1750 and came to North Carolina. Johnson, a Democrat from Tennessee, ran afoul of the Republicans in Congress who opposed his leniency toward the former Confederate states after the Civil War. He was the first president impeached by the House of Representatives but was acquitted.

> Party: Republican
> Term: 1869-77 (18th president)

Civil War hero Ulysses S. Grant became the first American president to visit Ireland in 1879 as part of his world trip after he left office. Grant’s Irish heritage came from his mother’s side. His maternal great-grandfather, John Simpson, came from Dergenagh, in County Tyrone in Ulster. As the nation’s 18th president, Grant ended Reconstruction, however, his administration was also marred by financial scandal.

6. Chester A. Arthur (1829-1886)

Chester A. Arthur, who became president following the assassination of James Garfield in 1881, had Irish lineage on his father’s side.
