Yes, it's the Pennsylvanian German Dialect.
German, Pennsylvanian German, and Pennsylvanian Dutch are all correct answers in this case.

In parts of Pennsylvanian, they celebrate groundhog day by holding a Fersommling, a party where the only language allowed to be spoken is Pennsylvanian German.

Congratulations!
