LONDON - President Obama was to visit Ireland today and the tiny village of Moneygall, home of his great-great-great grandfather on his mother's side.

The president's quick stop in Ireland will begin a six-day trip across Europe that will include a state visit to the United Kingdom, talks about Libya and the Arab Spring with allies at a summit in France.

It will also involve and an effort to smooth over relations with Poland and Central Europe after his administration canceled plans to build a missile-defense system there.
