German Immigration to America
Around 1670 the first significant group of Germans came to the colonies, mostly settling in Pennsylvania and New York. In 1709 a group known as the Palatines made the journey from the Palatinate region of Germany. Many died on the way over on crowded ships, but around 2,100 survived and settled in New York.
Soon after that, multiple waves of Germans arrived in the Southeast and settled in Virginia, North Carolina and Georgia. Another wave came and settled in New England.
Between 1725 and 1775 many Germans arrived and settled in Pennsylvania. By the beginning of the Revolutionary War, about 1/3 of the state was Germans.
