Schmidt
While the last name Smith originated in England, it eventually spread to other European counties. The last name then took on different variations depending on the local languages. For example, Schmidt is essentially the German version of Smith.
The last name was common among blacksmiths who lived in Germany and Austria, and Denmark. Today, Schmidt is known for being a Jewish last name, but since it is derived from an occupation, there is no sure way of knowing its religion based on their last name alone.
