First found in Germany, where the name Dahlman was among the notable families who contributed to the development of feudal society during the Middle Ages. The family became prominent in local affairs and its members married into other distinguished families, some of whom played important roles in the savage tribal and regional conflicts of this period.

Some of the first settlers of this family name or some of its variants were: Joh Dallmann, who settled in America in 1732. Peter Dahlmann came to Philadelphia in 1752; Frederic Talmon settled in Pennsylvania in 1754; Gustaf Heinrich Dalman arrived in Philadelphia in 1799.
