Yes, you only get the lord fame once.
If I haven't looked at your family page, but I think you currently have 1,4,5 and I'm not sure of two cause you need two character to get 10 prestige each. However, if you do have two char with over 10 prestige each then you have 2 also. Coming to 4 Fame.
Hoard your gold and stash it to you family... Will become useful later when you wish to create more characters.
Unique items are not each to come by that is for certain, though I have rather good luck.
