An Irish-born mariner who played a critical role in support of the American Revolution was commemorated Saturday with a ceremony at Southport Harbor, a port from which he had set sail.

The ceremony on Perry’s Green next to the harbor was organized by the Ancient Order of Hibernians to mark the tenth anniversary of federal legislation recognizing Commodore John Barry as the first flag officer of the U.S. Navy.

Barry, according to James Murray, the president of the Fairfield County chapter of the Hibernians, was born in Ireland’s County Kerry. Later in life, Barry became what Murray described as the “father of the American Navy,” who “fired the first and last volley in America’s war for independence.”

In addition to officials of the Ancient Order of Hibernians on hand for the harborside ceremony, a number of town and state officials also attended, including First Selectman Michael Tetreau, state Sen. Tony Hwang and state Rep. Laura Devlin.
