Here's a quick list I compiled of 'Official' Noble Families mentioned that may be of some help to GMs and Players alike. I've thus far only listed the House not specific members nor have I included Navigator Families nor Rogue Trader Families. Hope its useful, let me know if there are any mistakes or omissions, which is likely as this was just a quick 'casual pass'. I'll likely make more detailed entries later, feel free to add your own, Noble house used in your games or ones from suplements I may have missed.
