Latvians sometimes bore surnames derived from their profession (much like many other places in the world). Here are some I’ve come across:
Latvian (English) German
Arajs (Ploughman) Pfluger
Bruveris (Brewer) Bruhwer/Brauer
Kalejs (Blacksmith) Schmidt
Melderis (Miller) Meldehr/Mueller
Murnieks (Mason) Muhrneek/Maurer
Smits (Smith) Schmidt
Strelnieks (Rifleman) Strehlneek/Schuetzen
Stelmahers (Wheel Maker) Stellmacher
Veveris (Weaver) Weber
Occasionally these names are combined with other decriptive words or nouns, German or Latvian, eg: “Ironsmith” could be Dzelzkalejs or Eisenschmidt.
