That has a very "part of the crew, part of the ship" feeling to it. Work the land, become the land, you're named for the land that you work! With marital status, who your father was, your family's occupation, and where you're working, all in a name, résumés needn't be a thing.
Another difference between northern and southern Germany is the Munich-Du and the Hamburg-Sie. In standard German we use the formal pronoun Sie with the last name in formal situations and the informal pronoun Du with the given name in informal situations. Nowadays in semi-formal situations, like between colleagues at work, it's completely informal but two or three decades ago it wasn't. Officially the workplace was supposed to be formal and often it was, but in many cases a mixture between formal and informal forms was common.
In the north people tended to use the formal Sie but in conjunction with the given name, like Markus, können sie bitte das Auto holen." (Marcus, can thee get the car, please.), whereas in Bavaria the opposite combination of informal Du combined with the family name was prevalent, like *"Du, Frau Müller, kannst Du bitte das Auto holen." (You, Mrs. Miller, can you get the car please.)
Two notes:
First, you'd use "thou" here, as it's the nominative case, and the correct conjugation would be "canst".
Secondly, "thee" and "thou" were very much the form used to speak to a close friend or social inferior in early modern English. "You" functioned more like French "vous" or German "Sie"- as either a plural formation or a formal address of a social superior.
With that in mind, it would probably be more accurate to say that they should be rendered "Marcus, can you get the car, please?" and "Mrs. Miller, canst thou get the car, please?" And notice the parallel between "canst thou" and "kannst Du"!
I disambiguate my grandparents via the name of the farmhouse they live in, rather than the last names. I am from austria. But I dunno how common that is.
But those informal regional order conventions? I read them as formalized disrespect for the individual: "you're not Hans who happens to be a Müller, you're a Müller who happens to be Hans. And the Müllers, they are part of us, so subsume!" Those regional things can be quite peculiar: a childhood memory of my mother (northern Germany) is that as a child she was sometimes referred to as given name + name of the family farm, I suspect not in that order. With that farm's name still being the name of the family that ran ran it before her family took over, at some point between the thirty years war and the industrial revolution.
