The name Smith is not so much a meaning as the name of an occupation. Blacksmiths, silver smiths, copper smiths and other workers in metal were often known as "Jack the smith" or "Harry the goldsmith" etc in their communities. As occupational descriptions slowly converted into surnames, the name "Smith" came to be one of the most common, because each city and town needed more than one metal smith, so there were a lot of Smiths.
