Wanderers are procedurally generated based on certain defined templates. The templates pre-define certain things like the culture, gender, skills, gear, etc. and have a title associated with them, so they get generated as like "<random culture name> the Surgeon".I'm convinced there are procedurally generated wanderers. Either from a character pool list or even outright generated.
Someone compiled a list of all the different wanderers who can currently spawn in the beta:
