October is Polish American Heritage Month. The National Genealogical Society is pleased to share with you the following article on researching your Polish roots. Polish immigration to the United States began with the Jamestown settlement in 1608 when the Virginia Company hired Polish artisans skilled in trades needed in the new settlement.[1] Count Kazimierz Pulaski and Tadeusz Kościuszko distinguished themselves as heroes during the Revolutionary War. They were joined by about one hundred other Poles who fought alongside the Americans in the cause of freedom. Throughout US history, Polish immigrants have been arriving in the United States, with immigration peaking between 1870 and the start of World War I.
