I dont think that s the way it goes. Its just that if there was 1 smith in a village he was identified as such. The occupation had to be rare and important ( eg they wouldn t call you farmer. His children would keep the name regardless of their job (given that ppl had a lot of kids and the job had to be rare it s impossible that they d all do the same job)
