The March 2023 U.S. Presidential Proclamation

During Irish-American Heritage Month, I think of my great-great grandparents — the Blewitts of County Mayo and the Finnegans of County Louth.  Like so many other Irish immigrants who sought a new beginning in the United States, they arrived on our shores with hearts full of hope and dreams of the future.  With grit and determination, they worked hard.  And as they built their lives, they helped build America — never forgetting where they came from, always remembering the courage and pride they brought with them from the old country, and passing these traits down to each new generation. 

Irish Soldiers in the Union Army

Since before the founding of our Nation, Irish immigrants have arrived on our shores with an unyielding spirit of determination that has helped define America’s soul and shape our success across generations.
