Was told the word "Deutsch" means German in that language. First settlers to New Amsterdam [NY] were Dutch, Walloon, and Huguenot. They expanded to [now] New Jersey and western Long Island and up the Hudson River, and controlled the area from 1610-1664 when the English took over and named the city, New York. They were not deprived of their land or customs. Around the same time, 1664+, William Penn invited German immigrants to his new colony of Pennsylvania. Thousands came. Famous as industrious settlers. Palatine Germans fleeing the religious wars, passed through England to NY's Hudson Valley with the aid of Queen Anne ca 1701. But they found that there was no free land along the Hudson River, only the large Dutch and English manors. In discontent many moved to Pennsylvania, some stayed in NY in towns like German Flats, and up along the Mohawk Valley. So both Dutch and Germans in NY. So I have used the term, Pennsylvania Dutch, to mean Pennsylvania German.
