Migration of the Thomasius family

The great European flow of migration to North America, which began in the middle of the 17th century and continued into the 20th century, was particularly attractive to those from Bavaria who wished to escape either poverty or religious persecution. For many Bavarian tenant farmers, the chance to own their own land was a major incentive. So the widespread colonization of the United States began in 1650, when many immigrants from Germany settled in pockets in Pennsylvania, Texas, New York, Illinois, and California. In Canada, German settlement centered in Ontario and the prairie provinces. Among those of this surname listed in various historical records were: Matheus Thomas, who sailed for America in 1709 with his wife and daughters. Heinrich Thomas also came in 1709; settling in Carolina of Pennsylvania. Johann Philip Thoma came to Philadelphia in 1764.
