Frosch Family History

German: from Middle High German vrosch ‘frog’ applied as a nickname for someone thought to resemble a frog perhaps because he had bulging eyes (a common symptom of a disorder of the thyroid gland).

In some instances, it was also used as a topographic or habitational name.

This referred to a house distinguished by the sign of a frog.

The association with the character of a frog might have stemmed from the physical features of individuals.

This highlights the creative use of language in naming conventions within German culture.
