President Barack Obama celebrated a small piece of his heritage this St. Patrick’s Day and announced he would visit Ireland, including the village of Moneygall, the homeland of his great-great-great-grandfather.

IRELAND-USA/Or maybe it’s five ‘greats’, as he said in the Oval Office this morning? Either way, he’s confident he’s a little bit Irish.

“Two years into my presidency, some are still bent on peddling rumors about my origins.  So today I want to put all those rumors to rest,” he joked at the Friends of Ireland luncheon that he attended at the Capitol with Irish Prime Minister Enda Kenny. ” It is true my great-great-great-grandfather really was from Ireland.”

“I can’t believe I have to keep pointing this out,” Obama said.

House Speaker John Boehner, Irish Ambassador to the United States Michael Collins and others joined the president and prime minister (or taoiseach) for crab salad and roast Angus beef.
