ties were with County Antrim and County Kildare and County Cork. Jimmy Carter (Scotch-Irish & English) 39th President 1977–1981 (County Antrim) Ronald Reagan (Irish, English & Scottish) 40th President 1981–89: He was the great-grandson, on his father's side, of Irish migrants from County Tipperary who came to America via Canada and England in the 1840s. His mother was of Scottish and English ancestry. 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. Bill Clinton (Irish, Scotch-Irish & English) 42nd President 1993–2001: He claims Irish ancestry despite there being no documentation of any of his ancestors coming from Ireland George W. Bush (Irish, Scottish, Dutch, Welsh, French, German & English) 43rd President 2001–09: One of his five times great-grandfathers, William Holliday, was born in Rathfriland, County Down, about 1755, and died in Kentucky about 1811–12. One of the President's seven times great-grandfathers, William Shannon, was born somewhere in County Cork about 1730, and died in Pennsylvania in 1784. 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. His great great grandfather, Falmouth Kearney, was born in the Irish town of Moneygall.
