People of Irish descent are the second largest self-reported ethnic group in the United States, after German Americans. Nine of the signatories of the American Declaration of Independence were of Irish origin. Among them was the sole Catholic signatory, Charles Carroll of Carrollton, whose family were the descendants of Ely O'Carroll, an Irish prince who had suffered under Cromwell. At least twenty-five presidents of the United States have some Irish ancestral origins, including George Washington. Since John F. Kennedy took office in 1961, every American President (with the exception of Gerald Ford and Donald Trump) has had some Irish blood. An Irish-American, James Hoban, was the designer of the White House. Commodore John Barry, who was born in County Wexford, was the "Father of the United States Navy".
