(Northern Crown) - Crime Drama and Surname Etymology

I finally got my book at Origins.

I thought about how I could make this setting interesting to the others in my roleplaying group. I like the crime dramas on TV like Law and Order and CSI. I figured maybe I could make some characters along these lines. Here is what I have come up with:

The Police on Law and Order would be some kind of Paladins. The CSI would possibly Natural Philosophers.

I wonder would anyone else know how to convert "The Shield" and "The Wire."

Also, does any know of any website with period names and meanings.
