Maybe. Often when families immigrated to America they tried to pick a spelling that would allow English speakers to pronounce their name close enough to what they were used to that they would understand they were being called. Sometimes the this was a different English word that had nothing to do with the meaning in the original language. (I suspect the same happens with immigrants elsewhere, but I know my family name is based on getting close to the original sound and that happens to be a word that has a different meaning in English)
I don't know if the original word was a occupation back in the old world or not. (the dialect my family spoke is no longer spoken so it would be difficult to research)
