Admittedly it seems less common, but... there certainly are some Smeds in Sweden (and the rest of Scandinavia). The names are not ALL sons/sens and geographic features... https://forebears.io/surnames/smed
Less common is an understatement. Less than 300 people have Smed(h) as their surname in Sweden. We also don't know if they originated in Sweden or if this was a Swedification of a foreign surname.
