On the various displays that show game characters, the relationships are shown. In the Court look at the far right. PLYR, FMLY and NPC are the relationship descriptions. In the household affairs, look at the left. You see NPC next to NPC's, and a code showing the relation for your family. Like "Son", "Dght", "Rlt" (Rlt = Related, e.g. daughter in law..) If there is an asterisk (*) after the relationship (as in RLT*), then that character is serving as one of your bailiffs.
