I think I got the titles and administration figured out now. As for economy we will most likely use English names for money because it's less confusing. German ones are a tongue twister and too hard to remember, me thinks.

It will look something like this.

1 pound=20 shillings

1 shilling= 12 pence

1 pound= 240 pence


I'm yet to figure out salaries for different troops and tax revenues, income from mining, fields, fishing, etc. 
By the way guys, do you know what kind of jobs people of gentle birth did? Other than being military leaders, soldiers and church members. Like, it doesn't seem there's a lot of career possibilities for nobles. Once we get a navy I guess admiralty will also be an option, but that falls under military leader as well. Could they be merchants or just hire merchants to work for them as a source of income? I guess diplomats, bailiffs and such were also jobs for nobility.
