First found in Prussia, where this family name became a prominent contributor to the development of the district from ancient times. Always prominent in social affairs, the name became an integral part of that turbulent region as it emerged to form alliances with other families within the Feudal System and the nation.

The state of Prussia was a great influence on the shape of modern Germany. After the Second World War, Prussia's land was divided among the Soviet Union, Poland, East Germany and West Germany and the state was abolished. Some Prussians remained in those countries after the war, while many others migrated to North America in search of a new start. Philadelphia was their primary point of entry to the United States, after which many of them moved on to Ohio, Texas, Illinois, California, New York, and Maryland. A large number of Prussians also migrated to Ontario and the prairie provinces as United Empire Loyalists. Analysis of immigration records has shown some of the first Douchs to arrive in North America, and among them were: Amalie Catharina Deutsch, who settled in America in 1854; Carl Deutsch settled in Texas in 1846; Rudolph Deutsch settled in Philadelphia in 1880; Levi Deutsch, age 15.
