More than a century and a half ago, 19-year-old Falmouth Kearney, Obama’s third great-grandfather, sailed from Ireland, landing in New York harbor on March 20, 1850.
Settling initially in Ohio among Irish relatives, Falmouth married, had eight children, and eventually moved to Indiana. Three of Falmouth’s daughters married three brothers with the last name Dunham. Obama’s mother is descended from one of these couples — her birth name was Dunham.
Falmouth was among the thousands of Irish immigrating to America to escape the late 1840s potato famine in Ireland. By 1860, New York City had the largest Irish population in the world — a quarter of its residents had been born in Ireland.
If Obama succeeds in his presidential aspirations, he won’t be the first Commander in Chief with ties to Ireland. Ronald Reagan’s great-grandfather, Michael O’Regan, was born in Ireland in the 1820s, as was John F. Kennedy’s great-grandfather, Patrick Kennedy.
