Well, I suppose we shouldn't wait any longer. The remaining two people haven't been on the forum for the past few days so I will assume they are busy in real life for the time being.

I used [url]https://www.random.org/dice/[/url] to pick from the 6 existing families. Results:
1) thorgili - House Von Graffe (Counts of Greinburg)
2) Gowia - House Von Hoffendolt (Counts of Rastenburg)
3) mrambo90 - House Vlkové (Counts of Lichtenau)
4) UltikanaRe - House De Fleurs (Counts of Dobersberg) 

Also, do not take all towns/castles/villages in your counties. Leave some for the "vassal" houses of your respective counties. Fiefs of one's house do not necessarily need to be within one county.
