34 million Americans have Irish ancestry, according to the 2003 US Census. That's almost nine times the population of Ireland, which has 4.1 million people.

Nine of the people who signed our Declaration of Independence were of Irish origin, and nineteen Presidents of the United States proudly claim Irish heritage -- including our first President, George Washington.  

One estimate suggests that there are about 10,000 regular three-leaf clovers for every lucky four-leaf clover.

Legend says that each leaf of the clover means something:

• the first is for hope,  
• the second for faith,  
• the third for love and  
• the fourth for luck.
